Abstract
There is currently a gap in the literature regarding education by and for genetic counseling (GC) students and genetic counselors. Since little is written about current strategies used in GC graduate programs, we conducted a qualitative semi-structured interview study of North American GC program directors to learn about their educational goals and practices. We recruited 25 program directors from the United States and Canada through the Association of Genetic Counseling Program Directors for interviews using a video conferencing platform. Interviews were recorded and transcribed, followed by content analysis to analyze education frameworks; processes of program planning and development; approaches and strategies for teaching and assessing GC core knowledge and skills; and systemic factors that influence GC education. We emphasized areas that are challenging to teach, particularly ethical, legal, and social issues (ELSI); disability issues; genomics; counseling skills; diversity, equity, inclusion, justice (DEIJ) issues; professional identity; research skills; and teaching skills. We found commonalities supported by standards and practice-based competencies and also a rich diversity of program cultures, approaches, and techniques for teaching and assessing genetic counseling skills. There was a consistent theme of integration across the program for all areas examined. A multilayered, comprehensive approach to DEIJ issues was advocated. Planned change was a logical outcome of program assessment, while unplanned change called for flexibility and creativity. The description of GC educational practices provides documentation of current approaches and strategies, guidance for new GC programs, and inspiration for continued evolution of existing GC graduate programs.

Abstract
Contracting is a skill used by genetic counselors (GCs) to establish a shared vision for the session. Ensuring that patients and GCs are aligned on expectations for the encounter allows GCs to meet patient needs and support patient autonomy. Although contracting is described in the practice-based competencies (PBCs), the process has not been systematically observed in practice. We sought to further elucidate the skills used for contracting within genetic counseling sessions through directed content analysis of transcripts from 148 simulated prenatal and cancer genetic counseling sessions. An a priori codebook and rating scale were developed based on four contracting sample skills described in the PBCs: (a) describing the genetic counseling process, (b) eliciting client concerns, (c) applying client concerns to a session agenda, (d) modifying the agenda in response to emerging concerns. The rating scale described the quality of each skill on a 4-point scale of "absent," "minimal," "adequate," and "excellent." The codebook and rating scale were pilot tested with 40% of transcripts (n = 60). Three authors independently coded and rated the final 60% of transcripts (n = 88), resolving discrepancies via a consensus process. We found that the four PBC skills were present in most sessions (88%-98%), and on average, GCs received "adequate" scores on all four skills. We also identified three additional components of contracting not described in the PBCs: assessing whether client concerns were met, inviting to interrupt, and providing opportunity for partner concerns. This study represents the first attempt to evaluate GC performance of a PBC during a genetic counseling session. Our findings demonstrate that the PBC sample contracting skills reflect practice and suggest that they can be used in assessment of the genetic counseling contracting process. This type of analysis could be adapted in the future to provide support for other standards of practice in the genetic counseling field.

Abstract
We defined orienting language in genetic counseling sessions as 'language intended to direct focus to a particular aspect of the counseling process; a physical, emotional, or cognitive space; or an outcome'. This is a concept expanding on the idea of 'orientation' statements in the genetic counseling literature. We propose that orienting language is an important component of effective communication in the genetic counseling process. Our goals were to document the presence of orienting language in genetic counseling sessions with practicing genetic counselors and simulated clients, categorize types of orienting language, and evaluate the purpose of this language. A sample of Genetic Counseling Video Project videotape transcripts was evaluated through consensus coding for orienting language. Orienting language was found to be abundant in the dataset evaluated. Each excerpt was coded for orienting language Strategies and Purpose. The six categories of Strategy codes identified were Logical Consistency, Providing Context, Guidance, Structuring the Session, Anchoring, and Procedural. The six categories of Purpose codes were Counselee Understanding, Guidance, Engagement, Promoting Effective Counselor/Counselee Interactions, Counselee Adaptation, and Relationship Building. Results support our expanded definition of orienting language, which was similar in both cancer and prenatal specialties and across years of counselor experience. Orienting language acts as a series of signposts to help clients navigate the sometimes complex and unfamiliar territory of a genetic counseling session. The introduction of this term into the genetic counseling literature allows its use by genetic counselors to be further evaluated and potentially incorporated into genetic counselor training.

Abstract
Advanced training for master's trained genetic counselors has been a topic for many years. In 2016, Baty et al. published a model of advanced training for genetic counselors that interconnects three grids: skills, paths, and positions. The purpose of this qualitative study was to assess how well this model of advanced training reflected the experiences of genetic counselors with advanced genetic counseling skills. Using purposive sampling and deductive content analysis, results of 17 interviews demonstrated that the 3-grid model of advanced genetic counseling skills, paths to attaining these skills, and positions which utilize advanced skills, described elements important for the interviewees' career development. Results suggested refinements to the model in terms of content and organization and also suggested that advanced training be conceptualized as an important element of a career lattice that includes both vertical and horizontal movement. This refined model of genetic counselor advanced training can foster profession-wide career development by stimulating new career paths and career development research.

Abstract
The first practice based competencies (PBCs) for the field of genetic counseling were adopted by the American Board of Genetic Counseling (ABGC), 1996. Since that time, there has been significant growth in established and new work settings (clinical and non-clinical) and changes in service delivery models and the roles of genetic counselors. These changes prompted the ABGC to appoint a PBC Task Force in 2011 to review the PBCs with respect to their current relevance and to revise and update them as necessary. There are four domains in the revised PBCs: (I) Genetics Expertise and Analysis (II) Interpersonal, Psychosocial and Counseling Skills (III) Education and (IV) Professional Development and Practice. There are 22 competencies, each clarified with learning objectives or samples of activities and skills; a glossary is included. New competencies were added that address genomics, genetic testing and genetic counselors' roles in risk assessment, education, supervision, conducting research and presenting research options to patients. With PBCs serving as the pre-defined abilities or outcomes of training, graduating genetic counselors will be well prepared to enter the field with a minimum level of skills and abilities. A description of the Task Force's work, key changes and the 2013 PBCs are presented herein.

Abstract
We studied communication in genetic counseling sessions conducted with an African American, Breast Cancer 1, Early Onset (BRCA1) kindred in the USA. The Roter Interaction Analysis System (RIAS) was used to code and compare two sessions of 46 participants (26 females and 20 males) before and after they underwent genetic testing. Three certified genetic counselors and one medical geneticist conducted the sessions. When compared to pre-test communication, most of the providers' post-test communication was devoted to the provision of biomedical information (including screening recommendations) with fewer questions and psychosocial statements. Clients contributed a similar proportion to the total session dialogue in pre- and post-test sessions (40%). A larger proportion of their post-test session was devoted to indicating receptiveness to provider information than in the pre-test session. We found when providers were informing clients that they were BRCA1 mutation carriers, they provided more biomedical and psychosocial information and asked more psychosocial questions than when talking with non-carriers. This study provides the first description of genetic counseling communication for pre- and post-test BRCA1 sessions with African American individuals.

Abstract
The educational and counseling models are often touted as the two primary professional approaches to genetic counseling practice. Yet, research has not been conducted to examine how these approaches are used in practice. In the present study, we conducted quantitative communication analyses of BRCA1 genetic counseling sessions. We measured communication variables that represent content (e.g., a biomedical focus) and process (e.g., passive listening) to explore whether genetic counselor approaches are consistent with prevailing professional models. The Roter Interaction Analysis System (RIAS) was used to code 167 pre-test genetic counseling sessions of members of a large kindred with an identified BRCA1 mutation. Three experienced genetic counselors conducted the sessions. Creating composite categories from the RIAS codes, we found the sessions to be largely educational in nature with the counselors and clients devoting the majority of their dialogue to providing biomedical information (62 and 40%, respectively). We used cluster analytic techniques, entering the composite communication variables and identified four patterns of session communication: Client-focused psychosocial, biomedical question and answer, counselor-driven psychosocial, and client-focused biomedical. Moreover, we found that the counselors had unique styles in which they combined the use of education and counseling approaches. We discuss the importance of understanding the variation in counselor communication to advance the field and expand prevailing assumptions.

Abstract
In this study, we apply an existing medical communication coding system to BRCA1 genetic counseling sessions, describe the session dynamics, and explore variation in session communication. The sample was comprised of 167 members of an identified BRCA1 kindred whose pretest counseling session was audiotaped and coded using Roter's Interaction Analysis System (RIAS). Three certified genetic counselors followed a research protocol that dictated areas to be covered in the counseling session. We found that it was feasible to code long, protocol driven BRCA1 sessions in a quantitative manner without the use of transcripts and capture the dialogue of all session participants. These findings support the use of RIAS in genetic counseling research. Our results indicate that these BRCA1 sessions were predominantly educational in nature with minimal dialogue devoted to psychosocial issues. We found that participant gender, presence of a client companion, and counselor identity influence session communication.

Abstract
This study investigated uncertainty in individuals undergoing genetic counseling/testing for breast/ovarian cancer susceptibility. Sixty-three individuals from a single kindred with a known BRCA1 mutation rated uncertainty about 12 items on a five-point Likert scale before and 1 month after genetic counseling/testing. Factor analysis identified a five-item total uncertainty scale that was sensitive to changes before and after testing. The items in the scale were related to uncertainty about obtaining health care, positive changes after testing, and coping well with results. The majority of participants (76%) rated reducing uncertainty as an important reason for genetic testing. The importance of reducing uncertainty was stable across time and unrelated to anxiety or demographics. Yet, at baseline, total uncertainty was low and decreased after genetic counseling/testing (P = 0.004). Analysis of individual items showed that after genetic counseling/testing, there was less uncertainty about the participant detecting cancer early (P = 0.005) and coping well with their result (P < 0.001). Our findings support the importance to clients of genetic counseling/testing as a means of reducing uncertainty. Testing may help clients to reduce the uncertainty about items they can control, and it may be important to differentiate the sources of uncertainty that are more or less controllable. Genetic counselors can help clients by providing anticipatory guidance about the role of uncertainty in genetic testing.

Abstract
Mutations in the BRCA1 gene are associated with an increased risk of breast and ovarian cancer in carrier women. An understanding of behavioral responses to BRCA1 mutation testing by mutation carriers and non-carriers is important to guide the clinical application of this new technology. This study examined the utilization of genetic testing for a BRCA1 mutation in high-risk individuals and the response of tested women with respect to interventions for early cancer detection and prevention. This study assessed the utilization of genetic testing for both men and women in a large kindred and the behavioral responses by women with respect to use of health care interventions during the 2 years following testing. Participants were offered BRCA1 mutation testing. Surveillance behaviors related to breast and ovarian cancer were assessed by computer-assisted telephone interviews at baseline (prior to genetic counseling and testing), 1-2 weeks, 4-6 months, 1 and 2 years after the provision of test results. Mutation carriers, non-carriers, and individuals of unknown mutation status were compared to determine the impact of test results. Utilization of genetic testing for both men and women are reported and, for women, mammography, breast self-exam, clinical breast exam, mastectomy, oophorectomy, transvaginal ultrasound, and CA125 screening were assessed. Of those fully informed of the opportunity for testing, 55% of the women and 52% of the men pursued genetic testing. With respect to mammography for women 40 years and older, 82% of mutation carriers obtained a mammogram in each year following testing compared to 72% of non-carrier women the first year and 67% the second year. This mammography utilization represents a significant increase over baseline for both mutation carriers and non-carriers. Younger carrier women also significantly increased their mammography utilization from baseline. Overall, 29% of the carrier women did not obtain a single mammogram by 2 years post-testing. At 2 years, 83% of the carrier women and 74% of the non-carriers reported adherence to recommendations for breast self-exam and over 80% of carrier women had obtained a clinical breast examination each year following testing. None of the carrier women had obtained a prophylactic mastectomy by 2 years after testing, although 11% were considering this procedure. Of carrier women 25 years of age and older who had at least one intact ovary at the time of testing, 46% of carriers had obtained an oophorectomy 2 years after testing, including 78% of women 40 years of age and older. The majority of carrier women (73%) had discussed their genetic test results with a medical doctor or health care provider. Our results indicate utilization of genetic testing by a majority of high-risk individuals who received information about testing. Both carriers and non-carriers increased their utilization of mammography and breast self-exam following testing. Oophorectomy was obtained by a large proportion of carrier women in contrast to mastectomy which was not utilized within the first 2 years following testing.

Abstract
The prenatal diagnosis of trisomy 20 mosaicism presents a challenge for practitioners and parents. The diagnosis implies an uncertain risk for an inconsistent set of physical and developmental findings, as well as a substantial chance for a child that is normal physically and developmentally. We report two girls (ages nine years one month and eight years one month) with normal intelligence and hypopigmented skin areas. Both girls were born after a prenatal diagnosis of trisomy 20 mosaicism in amniocytes. Case 1 had 83% and 57% trisomy 20 cells from two separate amniocenteses and Case 2 had 90% trisomy 20 cells from an amniocentesis. Trisomy 20 was confirmed after birth in urinary sediment (25%) and chorionic villus cells (15%) in Case 1, while cord blood lymphocytes (30 cells) and skin fibroblasts (50 cells) had only 46,XX cells. Trisomy 20 was confirmed after birth in urinary sediment (100%), placenta (100%), cord (10%), amniotic membrane (50%), and skin fibroblasts (30%) in Case 2, while cord blood lymphocytes (100 cells) had only 46,XX cells. This is the first report of a hypopigmented pigmentary dysplasia associated with isolated trisomy 20 mosaicism. Our patients are the oldest reported children with trisomy 20 mosaicism confirmed after birth.

Abstract
Advances in molecular biology and genetics have led to the identification of the breast/ovarian cancer susceptibility genes BRCA1 and BRCA2, along with tests to detect mutations in these genes. Although the appropriateness of BRCA1/2 genetic testing for children has been debated in the literature, little is known about the attitudes of individuals who have undergone cancer susceptibility testing. The present study focused on attitudes toward BRCA1 testing for children among 218 adults from a Utah-based kindred who had received BRCA1 test results. Results indicated that approximately one-fourth of the participants would permit BRCA1 testing for children under the age of 18. General attitudes about genetic testing were predictive of attitudes toward the testing of children. In addition, men and individuals without a BRCA1 mutation were more likely to agree that minors should be allowed BRCA1 testing. Individuals whose mother had been affected with breast cancer were less likely to permit testing for minors. Among parents of minor children, less than one-fifth indicated that they would want BRCA1 testing for their own children; carrier status was not predictive of attitudes toward testing their own children. As breast/ovarian cancer susceptibility testing continues to be disseminated into clinical settings, there may be an increase in the number of test requests for minors. The findings of the present study represent an important step in exploring attitudes about genetic testing of children among individuals who have received cancer susceptibility test results.

Abstract
Developmental data were abstracted from medical records on 50 trisomy 18 individuals ranging in age from 1 to 232 months and 12 trisomy 13 individuals ranging in age from 1 to 130 months. Data on the age when trisomy 18 and trisomy 13 children achieved developmental skills were collected from a larger group of 62 trisomy 18 individuals and 14 trisomy 13 individuals whose families filled out parent questionnaires. Developmental quotient (DQ), defined as developmental age divided by chronological age, averaged 0.18 for trisomy 18 and 0.25 for trisomy 13. There was a dramatic drop in DQ from infancy to later childhood. The highest DQs and the greatest variation in DQs were in the first 2-3 years of life. Developmental ages in 7 skill areas were significantly different, with daily living and receptive language having the highest values and motor and communication skills having the lowest. When chronological age was taken into account, there was no significant difference in DQs in the same 7 skill areas, although there was a trend that was similar to the pattern of differences with developmental age. Older children could use a walker, understand words and phrases, use a few words and/or signs, crawl, follow simple commands, recognize and interact with others, and play independently. Walking and some toileting skills were also reported for trisomy 13. Although individuals with trisomy 18 and trisomy 13 were clearly functioning in the severe to profound developmentally handicapped range, they did achieve some psychomotor maturation and always continued to learn.

Abstract
The natural history of trisomy 18 and trisomy 13 was investigated using data derived from parent questionnaires and medical records from 98 families with an index case of trisomy 18 and 32 families with an index case of trisomy 13. Data are presented on pregnancy, delivery, survival, medical complications, immunizations, growth, cause of death, cytogenetics, and recurrence risk. Half of the trisomy 18 babies were delivered by C-section. Fetal distress was a factor in half, and the only reason in a third of C-section deliveries. One minute Apgar scores were significantly lower in C-section and breech deliveries. There were more small for gestational age babies than in the general population, but most of the low birth weight newborns were small for gestational age, unlike the general population. Survival in this group of children was better than in other studies due to ascertainment bias. There were more girls than boys at all ages for both conditions, and the sex ratio decreased with time. Growth curves for length, weight, head circumference, and weight vs height are provided. Long-term survival did not appear to be due to mosaicism. We found no adverse reactions attributable to immunizations. At age 1 year there was an average of approximately 2 operations per living child. We report the second case of successful major cardiac surgery in a trisomy 18 child. Almost 70% of deaths were attributed to cardiopulmonary arrest. The sibling recurrence risk for trisomy 18 or trisomy 13 was 0.55%.

Abstract
We report the prenatal diagnosis of distal arthrogryposis type I by ultrasound at 18 wk gestation in a family with two other affected members (mother and sister of the fetus). The pregnancy was followed with serial ultrasounds, and the diagnosis was confirmed after birth. The clinical findings in all affected family members are described. A literature survey of prenatally diagnosed cases of multiple joint contractures is presented. These include cases with many different diagnoses. This is the first report of the prenatal diagnosis of distal arthrogryposis type I. It helps to illustrate the variability and prenatal natural history of the condition and the subtlety of the prenatal ultrasound findings.

Abstract
Although the genetic pattern in NF has been definitely established as autosomal dominant, more precise data regarding penetrance, natural history, prevalence, and heterogeneity are needed for the counseling of families. NF is the prototypic disorder for the study of the biologic mechanisms of variable expressivity. The widely cited prevalence figure of Crowe is probably too high; thus the mutation ratio estimation in NF is among the highest in man but close to other common Mendelian disorders. With the existing data on frequency of Lisch nodules and with future prospective date on café-au-lait spot development, an age-of-onset penetrance curve for NF could be constructed for genetic counseling purposes. The segmental form of NF is of interest as cases of this presentation may be helpful in studying the hypothesis of human somatic mutation when DNA analysis is available. Guidelines for routine evaluation and ongoing health supervision of individuals with neurofibromatosis need to be developed; multidisciplinary NF clinics and collaborative study groups are appropriate settings for this undertaking. Neurofibromatosis is an important disorder for the study of the psychodynamic processes that families experience in dealing with uncertainty.
