Midwives’ Approach to Genetic Diseases and Genetic Counseling in Denizli, Turkey

The purpose of this study was to evaluate Denizli midwives’ self-reported knowledge of genetic diseases and genetic counseling. Data was collected on forms that obtained information about midwives approaches to basic genetics, genetic disorders, and genetic counseling (response rate = 70.1%). The highest response rate of midwives describing themselves as “knowledgeable” about basic genetic information was for mitosis and meiosis with 4.8%, about genetic disorders was for phenylketonuria with 61.1%, and about genetic counseling was for recommending ultrasonography during pregnancy with 98.1%. The source for basic genetics information for 56.4% of participants was in their school level classes. None of the midwives felt that they had sufficient knowledge about genetic counseling or screening and 76.4% would like to attend an educational course. Even though the midwives have recognized their knowledge deficit they occasionally give genetic counseling. As a result of this study a genetics course is planned for midwives so they can actively participate in the prevention and early diagnosis of genetic diseases.     

Genetic Counseling—Stress, Coping, and the Empowerment Perspective

Historically one of the basic foundations of the genetic counseling process has been nondirectiveness; however, its definition and utility continues to be in question. There remains a need to develop genetic counseling interventions in order to qualify, quantify, measure, and enhance the genetic counseling process as well as to delineate the complex interactions of education and counseling that occur. We propose a framework for genetic counseling interventions utilizing an empowerment perspective and Lazarus and Folkman's adaptation of the theory of stress and coping. This model frames the genetic counseling process as one that promotes the autonomy of the individual by providing the individual with the tools required to make their own decisions and enhances coping and adjustment to the outcome of those decisions through control and mastery.     

Cancer Genetic Counseling: Communication and Counselees’ Post-Visit Satisfaction,Cognitions, Anxiety,and Needs Fulfillment

Little is known about the relation between communication during cancer genetic counseling and outcome. We assessed associations between counselor-counselee communication and counselee satisfaction, cognitions, anxiety, and fulfillment of major needs, corrected for pre-visit levels as appropriate. In total 171 consecutive new counselees, mainly referred for breast or colon cancer, received pre- and post-visit questionnaires assessing needs/fulfillment, knowledge, perceived control (PPC), anxiety (STAI), and satisfaction. Initial visits were videotaped and counselor eye gaze was recorded. Verbal communication was rated by Roter Interaction Analysis System (RIAS). Asking more medical questions was associated with lower satisfaction levels. Receiving more medical information was related to higher correct knowledge scores, higher reported fulfillment of some needs, and unrelated to perceptions of control. Receiving more psychosocial information and longer counselor eye gaze were related to higher anxiety scores. Longer visits were related to higher correct knowledge scores. Providing medical information appears the most powerful communication aspect to increase counselee satisfaction and address needs. More research is needed on how to address adequately (emotional) needs and increase feelings of control.     

Transmission of the Communicative Competence: Genetic,Cultural, When,and How?

Several recent contributions from various disciplines have improved the interpretation of determinants influencing the interrelated processes of speech acquisition, and cognitive and emotional development. The existence of precursors of abstract symbolisation and of words in the animal world suggest a continuity in the evolution of communicative capacities. In man, evolution has not only favoured a specific precocity in communicative development in infants, but also the co-evolution of a species-specific environmental support for speech acquisition in caretakers. Thus, speech acquisition results from both biogenetic predispositions and environmental support as it becomes evident in micro-analysis of parent-infant interactions and experimental verifications. The preverbal period of communicative development appears in a new light from theoretical and clinical views.     

Am I My Genes? Perceived Genetic Etiology,Intrapersonal Processes,and Health

With the increasing popularity and affordability of DNA sequencing through direct‐to‐consumer DNA sequencing services, it has become apparent that researchers need to understand how the results of sequencing one's DNA affects consumers psychologically and behaviorally. In this paper, the authors discuss several intrapersonal processes that may impact how learning about our own genetic predispositions affects us. In particular, this paper sets out to identify the interplay between three relevant perspectives: genetic essentialist biases, perceived identity, and need for certainty. These interrelated perspectives and the empirical research that supports relevant underlying predictions provide a useful basis from which researchers can further identify testable hypotheses on these intrapersonal perceived genetics effects. Such research has potential far‐reaching implications, not the least of which are in the health domain.     

Genetic Counseling, Activism and ‘Genotype-First’ Diagnosis of Developmental Disorders

This paper presents a sociological examination of the role of genetic counselors as advocates, not only for patients and their families, but also for genetic conditions themselves. In becoming activists for new disorders, genetic counselors are helping to create new categories that will shape expectations and treatment regimens for both existing patients and those who are yet to be diagnosed. By virtue of their expertise and their position at the intersection of several key professions and constituencies, genetic counselors are likely to play a central role in the way the genetic testing technologies, and especially ‘genotype-first’ diagnosis, impacts the way we understand and categorize developmental difference. I outline some of the promises and dangers that this kind of activism holds for people with developmental disabilities, and particularly the challenge presented by systemic ascertainment bias in the face of genotype-phenotype uncertainty. I argue that new testing techniques like microarray analysis that do not need to be targeted on the basis of clinical presentation throw these challenges into sharp relief, and that the genetic counseling community should consider how to marry advocacy for new genetic conditions with an emphasis on the indeterminate developmental potential of every child.     

A Comparison of Telephone Genetic Counseling and In-Person Genetic Counseling from the Genetic Counselor’s Perspective

Growing demand for and limited geographic access to genetic counseling services is increasing the need for alternative service delivery models (SDM) like telephone genetic counseling (TGC). Little research has been done on genetic counselors’ perspectives of the practice of TGC. We created an anonymous online survey to assess whether telephone genetic counselors believed the tasks identified in the ABGC (American Board of Genetic Counseling) Practice Analysis were performed similarly or differently in TGC compared to in person genetic counseling (IPGC). If there were differences noted, we sought to determine the nature of the differences and if additional training might be needed to address them. Eighty eight genetic counselors with experience in TGC completed some or all of the survey. Respondents identified differences in 13 (14.8 %) of the 88 tasks studied. The tasks identified as most different in TGC were: “establishing rapport through verbal and nonverbal interactions” (60.2 %; 50/83 respondents identified the task as different), “recognizing factors affecting the counseling interaction” (47.8 %; 32/67), “assessing client/family emotions, support, etc.” (40.1 %; 27/66) and “educating clients about basic genetic concepts” (35.6 %; 26/73). A slight majority (53.8 %; 35/65) felt additional training was needed to communicate information without visual aids and more effectively perform psychosocial assessments. In summary, although a majority of genetic counseling tasks are performed similarly between TGC and IPGC, TGC counselors recognize that specific training in the TGC model may be needed to address the key differences.     

What is Genetic Information,and why is it Significant? A Contextual,Contrastive, Approach

abstract Is genetic information of special ethical significance? Does it require special regulation? There is considerable contemporary debate about this question (the ‘genetic exceptionalism’ debate). ‘Genetic information’ is an ambiguous term and, as an aid to avoiding conflation in the genetic exceptionalism debate, a detailed account is given of just how and why ‘genetic information’ is ambiguous. Whilst ambiguity is a ubiquitous problem of communication, it is suggested that ‘genetic information’ is ambiguous in a particular way, one that gives rise to the problem of ‘significance creep’ (i.e., where claims about the significance of certain kinds of genetic information in one context influence our thinking about the significance of other kinds of genetic information in other contexts). A contextual and contrastive methodology is proposed: evaluating the significance of genetic information requires us to be sensitive to the polysemy of ‘genetic information’ across contexts and then examine the contrast in significance (if any) of genetic, as opposed to nongenetic, information within contexts. This, in turn, suggests that a proper solution to the regulatory question requires us to pay more attention to how and why information, and its acquisition, possession and use, come to be of ethical significance.     

Gay, Lesbian, and Bisexual Patients’ Recommendations for Genetic Counselors: A Qualitative Investigation

Gay, lesbian, and bisexual (GLB) individuals comprise a growing patient population in genetic counseling. However, only one article from a genetic counseling journal provides empirical data on GLB patients' genetic counseling experiences and genetic counselor attitudes and practices regarding GLB patients. The present study, an extension of the aforementioned article, gathered further information about patients' genetic counseling experiences through semi-structured telephone interviews. Twelve of the previous study's 29 patient respondents (n?=?10 lesbian women, n?=?1 gay man, n?=?1 bisexual woman) participated. Interview questions concerned the use of medically inclusive forms, factors influencing patient disclosure, counselors' ability to relate to them, and their expectations of genetic counselors. Inductive analysis of the interviews yielded seven themes: 1) Medically inclusive forms with gender neutral terms are important; 2) Genetic counselor ability to relate to a GLB person depends more on the relationship established during the session and less on external symbols; 3) The presence of GLB-friendly symbols increases comfort when disclosing one's orientation; 4) Inclusion of the patient's partner is important and best done by encouraging their active participation in sessions; 5) When GLB patients disclose their orientation, they expect to be treated like any other patient; 6) Providers should ask about orientation if medically pertinent and the remaining discussion should take orientation into consideration; and 7) When a provider inquires about orientation it should be done in a safe and appropriate way. Illustrative quotations, genetic counseling practice implications, and research recommendations are presented.     

Primary Care Physicians’ Awareness, Experience and Opinions of Direct-to-Consumer Genetic Testing

The purpose of this study was to assess primary care physicians’ awareness, experience, opinions and preparedness to answer patients’ questions regarding direct-to-consumer (DTC) genetic testing. An anonymous survey was mailed to 2,402 family and internal medicine providers in North Carolina. Of the 382 respondents, 38.7% (n = 148) were aware of and 15% (n = 59) felt prepared to answer questions about DTC genetic tests. Respondents aged 50 or older were more likely to be aware of DTC genetic testing than those less than 40 years old (OR = 2.42). Male providers were more likely to feel prepared to answer questions than female providers (OR = 2.65). Among respondents who reportedly were aware, family practitioners were more likely than internists (OR = 3.30) to think DTC testing was clinically useful, and 18.9% had patients ask questions or bring in test results. The small percent of physicians who were aware of DTC genetic testing or felt prepared to answer questions about it suggests that education of providers will be necessary if testing becomes more widespread.     

Why aren't identical twins linguistically identical? Genetic, prenatal and postnatal factors

Results of twin studies clearly demonstrate that genetic factors play an important role in the rate of language acquisition and linguistic proficiency attained by normal and impaired children and adults [see Stromswold, K. (2001). The heritability of language: A review and meta-analysis of twin, adoption and linkage studies. Language, 77, 647-723.]. That said, twin-based heritability estimates for language rarely exceed .6 and monozygotic (MZ) twins (who are usually assumed to have identical genetic and environmental endowments) sometimes have very different linguistic profiles. In addition, twins are more likely to suffer linguistic delays and impairments than singletons. Postnatal factors, such as differences in linguistic input twins receive, are usually assumed to be the major reason for these findings. This paper discusses how genetic, epigenetic, and perinatal environmental factors can lower heritability estimates for language, cause MZ twins to be linguistically discordant, and increase the risk of language impairments in twins. We present results from our ongoing Perinatal Environment and Genetic Interaction (PEGI) study that suggest that perinatal environmental factors affect linguistic development more than postnatal factors, and that postnatal factors affect cognitive development more than perinatal factors. Because perinatal factors are overwhelming biological, whereas postnatal factors tend to be psychosocial (e.g., how and how much parents speak to their children), these results support nativist/biological theories of language and language development and call into question empiricist/emergentist theories. These results are also consistent with modularist theories of language. We end by suggesting new methods that can be used to tease apart the effects of prenatal and postnatal environment and to investigate how these factors interact with genetic factors.     

Parkinson’s Disease: Patients’ Knowledge,Attitudes, and Interest in Genetic Counseling

The objective of this study was to assess the genetics knowledge of patients with Parkinson’s disease (PD), and to explore their attitudes on genetic testing and interest in genetic counseling. We surveyed 158 patients from the University of Maryland Parkinson’s Disease and Movement Disorders Center. Patients averaged a score of 63% on general genetics knowledge and 73% on PD genetics knowledge. Participants had an overall positive attitude toward genetic testing: 80% believed that the use of genetic tests among people should be promoted, and 83% would undertake genetic test for PD if it was available. Patients reported a high interest to discuss the benefits, risks, and impacts of genetic testing for PD (mean sum score?=?26, range?=?9–35), and 43% patients expressed interest in meeting with a genetic counselor. Multivariate regression analysis showed that patients who had more positive attitudes toward genetic testing for PD were more interested in meeting with a genetic counselor (β?=?0.6, p?<?0.001). This study is the first to demonstrate an interest in genetic counseling among patients with PD. Our findings demonstrate a new niche for genetic counselors to support patients in clarifying gaps or misconceptions in knowledge about PD genetics as well as the possible risks, benefits, and limitations of genetic testing.     

Genetic Counselors’ Perspectives About Cell-Free DNA: Experiences,Challenges, and Expectations for Obstetricians

The expansion of cell-free fetal DNA (cfDNA) screening for a larger and diverse set of genetic variants, in addition for use among the low-risk obstetric population, presents important clinical challenges for all healthcare providers involved in the delivery of prenatal care. It is unclear how to leverage the different members of the healthcare team to respond to these challenges. We conducted interviews with 25 prenatal genetic counselors to understand their experience with the continued expansion of cfDNA screening. Participants supported the use of cfDNA screening for the common autosomal aneuploidies, but noted some reservations for its use to identify fetal sex and microdeletions. Participants reported several barriers to ensuring that patients have the information and support to make informed decisions about using cfDNA to screen for these different conditions. This was seen as a dual-sided problem, and necessitated additional education interventions that addressed patients seeking cfDNA screening, and obstetricians who introduce the concepts of genetic risk and cfDNA to patients. In addition, participants noted that they have a professional responsibility to educate obstetricians about cfDNA so they can be prepared to be gatekeepers of counseling and education about this screening option for use among the general obstetric population.     

Emerging Genetic Counselor Roles within the Biotechnology and Pharmaceutical Industries: as Industry Interest Grows in Rare Genetic Disorders,How are Genetic Counselors Joining the Discussion?

Traditionally, the biotechnology and pharmaceutical industry (BPI) has focused drug development at the mass-market level targeting common medical issues. However, a recent trend is the development of therapies for orphan or rare disorders, including many genetic disorders. Developing treatments for genetic disorders requires an understanding of the needs of the community and translating genomic information to clinical and non-clinical audiences. The core skills of genetic counselors (GCs) include a deep knowledge of genetics and ability to communicate complex information to a broad audience, making GCs a choice fit for this shift in drug development. To date there is limited data defining the roles GCs hold within this industry. This exploratory study aimed to define the roles and motivation of GCs working in BPI, assess job satisfaction, and identify translatable skills and current gaps in GC training programs. The authors surveyed 26 GCs working in BPI in the United States; 79 % work for companies focused on rare disorders. GC positions in BPI are growing, with 57 % of respondents being the first GC in their role. GCs in BPI continue to utilize core genetic counseling competencies, though 72 % felt their training did not fully prepare them for BPI. These data suggest opportunities for exposure to BPI in GC training to better prepare future generations of GCs for these career opportunities. GC satisfaction was high in BPI, notably in areas traditionally reported as less satisfying on the National Society for Genetic Counselors Professional Status Survey: salary and advancement opportunities. BPI’s growing interest in rare disorders represents a career opportunity for GCs, addressing both historic areas of dissatisfaction for GCs and BPI’s genomic communication needs.     

Just Ignore It? Parents and Genetic Information

This paper discusses whether prospectiveparents ought to find out about their geneticconstitution for reproductive reasons. It isargued that ignoring genetic information can bein line with responsible parenthood or perhapseven recommendable. This is because parenthoodis essentially an unconditional project inwhich parents ought to commit themselves tonurturing any kind of child. Besides, thetraditional reasons offered for theunfortunateness of impairments and the tragicfate of families with disabled children are notconvincing. Other morally problematic outcomesof genetics, such as discrimination againstindividuals with impairments, and limiting freeparental decision making, are alsoconsidered.
