Family history information comprises an important tool in identifying and referring patients at risk for hereditary breast and ovarian cancer (HBOC) to cancer genetic counseling. Despite recommendations and support provided by numerous professional organizations, cancer genetic counseling services are underutilized by atrisk patients. This study aimed to: (1) determine the rate of genetic counseling utilization following a referral letter, (2) characterize factors (barriers and supports) which influenced uptake of services, and (3) identify potential strategies for increasing utilization. This study evaluated the uptake of cancer genetic counseling among 603 screening mammography patients identified as having an increased risk for HBOC based on National Comprehensive Cancer Network (NCCN) guidelines. At risk individuals and their primary care providers were mailed a referral letter recommending genetic counseling. Three focus groups ( N  = 24) were conducted to identify responses to receiving a letter recommending genetic counseling, barriers to seeking genetic counseling, and facilitating factors to utilizing these services. Participant responses were qualitatively analyzed using thematic and cross case analysis. Within one year, 50/603 (8 %) of the identified at-risk women completed a genetic counseling appointment. Participant-perceived barriers which influenced their decision not to seek genetic counseling included lack of relevance and utility, limited knowledge about genetic counseling, concerns about the genetic counseling process, and concerns about cost and insurance coverage. Participant-perceived facilitating factors which would support a decision to seek genetic counseling included greater awareness and education about genetic counseling services when receiving a referral, and improved follow up and guidance from their provider. Findings from this study support the need for patient and primary care provider education, and improved provider-patient communication to increase uptake of genetic counseling services.

Direct-to-consumer personal genomic testing (DTC-PGT) results lead some individuals to seek genetic counseling (GC), but little is known about these consumers and why they seek GC services. We analyzed survey data pre- and post-PGT from 1026 23andMe and Pathway Genomics customers. Participants were mostly white (91%), female (60%), and of high socioeconomic status (80% college educated, 43% household income of ≥$100,000). After receiving PGT results, 43 participants (4%) made or planned to schedule an appointment with a genetic counselor; 390 (38%) would have used in-person GC had it been available. Compared to non-seekers, GC seekers were younger (mean age of 38 vs 46 years), more frequently had children <18 (26% vs 16%), and were more likely to report previous GC (37% vs 7%) and genetic testing (30% vs 15%). In logistic regression analysis, seeking GC was associated with previous GC use (OR = 6.5, CI = 3.1–13.8), feeling motivated to pursue DTC-PGT for health reasons (OR = 4.3, CI = 1.8–10.1), fair or poor self-reported health (OR = 3.1, CI = 1.1–8.3), and self-reported uncertainty about the results (OR = 1.8, CI = 1.1–2.7). These findings can help GC providers anticipate who might seek GC services and plan for clinical discussions of DTC-PGT results.

Based on nationwide data from the French national cancer institute (INCa), we analyzed the evolution of cancer genetics consultations and testing over time, and the uptake of targeted tests in relatives of families with BRCA1/2 or MMR genes mutation. Genetic testing and consultations for familial high-risk individuals are exclusively funded and monitored by the INCa in France. All nationwide cancer genetics centers reported annually standardized parameters of activity from 2003 to 2011. The analysis included a total of 240,134 consultations and 134,652 genetic tests enabling to identify 32,494 mutation carriers. Referral for hereditary breast and ovarian cancer (HBOC) or colorectal cancer predisposition syndromes represented 59 % (141,639) and 23.2 % (55,698) consultations, respectively. From 2003 to 2011, we found a dramatic and steady increase of tests performed for BRCA1/2 (from 2,095 to 7,393 tests/year, P  < 0.0001) but not for MMR genes (from 1,144 to 1,635/year, P  = NS). The overall percentage of deleterious mutations identified in the probands tested was 13.8 and 20.9 % in HBOC and Lynch syndromes, respectively. Pooled analysis for BRCA1/2 and Lynch syndrome tests showed an inverse relationship between the percentage of mutation detected and the absolute number of tests performed over the time (overall Cochran–Armitage test for trend: P  < 0.001). In families with BRCA1/2 or MMR identified mutations, there was an average number of 2.94 and 3.28 relatives performing targeted tests, respectively. This nationwide study shows a lack of referral and genetic testing in Lynch as compared to HBOC syndromes. Only a third of relatives of a proband with a predisposing mutation performed a targeted test. Enhanced information about benefit of genetic testing should be given to clinicians and patients for Lynch syndrome and relatives of a proband carrying an identified predisposing mutation.

We assessed the prevalence of TNFRSF13B mutations and the clinical correlates in an Italian cohort of 189 CVID, 67 IgAD patients, and 330 healthy controls to substantiate the role of TACI genetic testing in diagnostic workup. We found that 11% of CVID and 13% of IgAD carried at least one mutated TNFRSF13B allele. Seven per cent of CVID had monoallelic-mutations and 4% had biallelic-mutations. The frequency of C104R monoallelic-mutations was not higher than that found in healthy controls. Biallelic-mutations were exclusively found in CVID. CVID patients carrying monoallelic-mutations had an increased prevalence of lymphadenopathy, granulomata, and autoimmune cytopenias. CVID carrying biallelic-mutations had a low prevalence of autoimmunity in comparison with TACI wild-type CVID. Moreover, biallelic-mutated CVID had higher frequency of switched memory B-cells and higher IgM and IgA antibodies to polysaccharide antigens than TACI wild-type and monoallelic-mutated CVID. TACI-mutated IgAD patients had only monoallelic-mutations and did not display clinical difference from IgAD wild-type patients. In conclusion, TNFRSF13B genetic screening of antibody deficiencies may allow the identification of mutational patterns. However, as with counseling for risk assessment, geneticists should be aware that the interpretation of genetic testing for TACI mutations is difficult and the potential impact on clinical management is still limited.

The rise in the prevalence of autism spectrum disorder (ASD) has resulted in increased efforts to understand the causes of this complex set of disorders that emerge early in childhood. Although research in this area is underway and yielding useful, but complex information about ASD, guidelines for the use of genetic testing and counseling among children with ASD conflict. The purpose of this study was to determine the frequency of use of genetic testing and counseling before the widespread implementation of clinical chromosomal microarray (CMA) to establish a baseline for the use of both services and to investigate potential disparities in the use of both services among children with ASD. We found that about two-thirds of children with ASD received genetic testing or counseling and the use of both services is increasing with time, even in the pre-CMA era. Being female and having a comorbid intellectual disability diagnosis both increased the likelihood of receiving genetic testing and genetic counseling. Initial discrepancies in the use of both services based on race/ethnicity suggest that troubling disparities observed in other services delivered to children with ASD and other mental health disorders persist in genetic testing and counseling as well. These results should incentivize further investigation of the impact of genetic testing and counseling on children with ASD and their families, and should drive efforts to explore and confront disparities in the delivery of these services, particularly with the advancing scientific research on this topic.

The number of available genetic testing options and the nuances associated with these options continue to expand. In addition, the scope of genetic testing has broadened to areas and specialties beyond Medical Genetics. In response to these changes, diagnostic laboratories have employed genetic counselors to help navigate the increasing complexity of genetic testing, given their expertise and training in human genetics. However a largely unrecognized aspect of this role involves the use of counseling skills. Counseling skills are used by laboratory genetic counselors in a variety of situations to convey information and facilitate understanding among clinicians and medical staff. This helps to reduce test ordering errors, promote optimal test utilization, and ensure best patient care practices. The specific counseling skills used by laboratory counselors will be explored using three fictional case vignettes, followed by a discussion of the applicability of these skills in other contexts. Exploration of the unique ways in which laboratory genetic counselors apply their counseling skills can be useful for professional development and instructive for graduate training programs.

Continuing medical education (CME) is challenging and often has limited impact on clinician behavior or patient outcomes. This study examined the impact of an online Qstream education program on senior clinicians to determine its utility for increasing clinician knowledge about the latest guidelines regarding genetic assessment and consideration of genetic testing for women with particular types of ovarian, fallopian tube and primary peritoneal cancer. Participants were recruited into a pilot study that involved responding to case-based scenarios at spaced and repeated intervals. At the completion of the program, semi-structured interviews were conducted to ascertain the impact on their knowledge and referral behavior. Findings from interviews were subject to thematic analysis that involved the identification of categories and themes. Twenty-one participants commenced the program, seventeen completed and twelve participated in semi-structured interviews. Thematic analysis yielded several themes including knowledge change, curriculum and format and changes in referral patterns. A majority of participants ( n  = 10) agreed the program had helped update their knowledge about referring women, and eight agreed they would now change their referral patterns. The use of QStream as an approach to CME has significant advantages when working with busy clinicians. QStream has a well accepted format and most participants indicated it is very appropriate for disseminating updates to clinical guidelines and protocols. It is important to supplement CME programs with other implementation techniques, such as audit and feedback as multifaceted approaches are more likely to result in behavior change.

Genetic counselors believe fertility preservation and preimplantation genetic diagnosis (PGD) discussions to be a part of their role when counseling BRCA1/2 mutation-positive patients. This study is the first to explore reproductive endocrinologists’ (REI) practices and attitudes regarding involvement of genetic counselors in the care of BRCA1/2 mutation carriers seeking fertility preservation and PGD. A survey was mailed to 1000 REIs from Reproductive Endocrinology & Infertility (SREI), an American Society for Reproductive Medicine (ASRM) affiliate group. A 14.5 % response rate was achieved; data was analyzed using SPSS software. The majority of participating REIs were found to recommend genetic counseling to cancer patients considering fertility preservation (82 %) and consult with a genetic counselor regarding PGD for hereditary cancer syndromes (92 %). Additionally, REIs consult genetic counselors regarding PGD patient counseling (88 %), genetic testing (78 %), and general genetics questions (66 %). Two areas genetic counselors may further aid REIs are: elicitation of family history, which is useful to determine fertility preservation and PGD intervention timing (32 % of REIs utilize a cancer family history to determine intervention timing); and, interpretation of variants of uncertain significance (VOUS) as cancer panel genetic testing becomes more common (36 % of REIs are unfamiliar with VOUS). Given our findings, the Oncofertility Consortium® created an online resource for genetic counselors focused on fertility preservation education and communication strategies.

Rarely has utilization of genetic counseling for Hereditary Breast and Ovarian Cancer (HBOC) been studied separately from utilization of testing. At Kaiser Permanente Colorado, consistently only 30% of all members referred for HBOC attend genetic counseling. To increase the volume of genetic counseling appointments, a patient navigator approach was pilot tested in a randomized‐controlled trial over 3 months. A total of 125 members were referred for HBOC genetic counseling (55 randomized to PN, 70 randomized to usual care). Utilization of referrals for Navigator‐assisted members was 44%, compared to 31% in the usual care arm (p=0.16). The patient navigator significantly decreased time to appointment, with over 80% of Navigator‐assisted members seen for genetic counseling less than three months from referral date, compared to 32% in usual care (p=0.002). patient navigator assistance shortens time from referral to appointment for HBOC genetic counseling, and may increase utilization of such services.

Objective: Universal newborn screening for hemoglobinopathies started in The Netherlands in 2007. Herewith severe conditions, such as sickle cell disease, β-thalassemia major and hemoglobin H disease are putatively identified. Additionally, at least 1,800 carriers of hemoglobin variants associated with severe conditions in homozygote or compound heterozygote forms are identified yearly. Thus far, approximately 60 patients and 800 healthy sickle cell (HbS) carriers are reported each year among 180,000 newborns. Results are sent to the general practitioner with the recommendation to inform and diagnose both parents of the healthy carriers to exclude genetic risk, while patients and their parents are referred directly to a pediatrician. This study was performed to determine how often parents of identified carriers and affected newborns are seen in genetic centers for counseling. Methods: In this retrospective study, we collected anonymized data from 7 of the 8 Dutch clinical genetic centers from January 1, 2007, until December 31, 2010. Results: After an initial general increase in total counseling intakes, a decline was noticed in the third year, while the requests for prenatal diagnoses remained relatively stable. In 2007 and 2013, genetic counselors were asked for self-reported knowledge. They found hemoglobinopathy counseling complex, but by 2013, they indicated they had acquired sufficient knowledge on most hemoglobinopathy aspects. Conclusion: We could not observe a significant increase in genetic counseling for hemoglobinopathy after its introduction into newborn screening. Although 120 HbS carriers and 60 patients are expected to be born from couples at risk annually, only 33 at risk couples out of 540 families of diagnosed newborns received optimal care and information at a genetics center in 4 years.
