The first genetic counseling (GC) graduate training program was established in the United States (U.S.) in 1969 and GC is an emerging field of healthcare in many countries. Each year, at least 7% of applicants to U.S.-based GC graduate programs come from countries outside the U.S. ("international GC applicants''). To address the unique needs of international GC applicants, volunteers from the International Special Interest Group (ISIG) of the National Society of Genetic Counselors (NSGC) launched a semi-structured mentorship program (the "International Genetic Counseling Mentorship Program'' (IGCMP)) in 2021, which provides individualized mentorship and optional group activities for networking and learning. Fifty-two people from 19 countries signed up for the IGCMP across three application cycles. Of these, 47 were eligible to participate as mentees, and most were interested in one-on-one virtual meetings with international GCs in the U.S. (n = 41/47, 87.2%). An assessment form was sent to 17 mentees who applied to GC graduate school after participating in the first or second cycle of the IGCMP. Of the 12 responses received, 10 (83.3%) reported being extremely satisfied with their individual mentor(s), and the one-on-one meeting with a mentor was considered helpful to both the application and interview process by nine (75.0%) respondents. Importantly, feedback about program improvement revealed an interest in connecting with additional international applicants and mentors and all respondents expressed interest in receiving mentorship throughout graduate school. Future directions include collaborating with other mentorship and graduate programs to further enhance support for international applicants.

Latinas are less likely to receive genetic counseling and genetic testing (GCT) compared to non-Latina Whites because of systemic and patient-level barriers. We developed and tested fotonovelas to increase awareness of GCT among Latinas at-risk of hereditary breast and ovarian cancer (HBOC). Content for the fotonovelas was drawn from an existing culturally targeted narrative video focused on improving GCT use among Latinas at-risk of HBOC. Using mixed methods, we interviewed cancer patients (n = 10) and their relatives (n = 10) to assess the preliminary efficacy of the fotonovelas through pre-and post-fotonovela items assessing self-rated knowledge of GCT and willingness to discuss cancer with family. Health workers (n = 10) provided feedback on the fotonovela content. McNemar's test was used to examine differences in the proportions of the outcomes pre- and post-fotonovelas. Interviews were transcribed and coded in Dedoose using a consensual qualitative research approach. Reading the fotonovelas increased self-rated knowledge of GCT by 22% (p = 0.16), from 50 to 60% in patients and from 63 to 100% among relatives. Analogously, reading the fotonovela increased willingness to talk about cancer with family by 33% (p = 0.02), from 70 to 100% in patients and from 38 to 75% in relatives. We identified six themes, some centered around the fotonovela's message, feedback, and perceived barriers to GCT. Overall, participants liked the use of fotonovelas to increase GCT awareness and cancer conversations with family. Fotonovelas could potentially be used as educational tools to increase GCT awareness and cancer conversations among Latino families at-risk of HBOC.

This study describes the experiences with the stigma attached to Machado-Joseph disease (MJD) in São Miguel Island, the Azores (Portugal). We draw on semi-structured interviews with persons with MJD, family members, healthcare professionals, and direct care providers recruited through the local patient's association (n = 28). Qualitative thematic analysis revealed three main themes: (i) the intense stigma associated with MJD in the past; (ii) the current tendency towards increased openness; and (iii) increased availability of information about MJD and support. The findings suggest that stigmatization was more frequent and intense in the past. Still, there is currently a decrease in the intensity of perceived stigma, accompanied by an increasing awareness about MJD within the community. The local patient's association is noted for playing a pivotal role in raising awareness about MJD in the community and fostering the confidence of individuals with MJD and their families to engage socially, which may help to reduce or mitigate feelings of stigma. This raises questions about whether the diminished stigma towards MJD in São Miguel results from heightened awareness about the condition, a decrease in the social acceptability of stigma, or a gradual internalization and normalization of stigma among individuals with MJD as a coping mechanism.

Patients with hereditary breast and ovarian cancer (HBOC) are not only concerned about their own health but also about that of their children, grandchildren, and other relatives. Therefore, they have specific needs for information and support. During genetic counseling guidance is provided to HBOC patients and other individuals who may be at risk for familial cancer. The purpose of the study was to identify the needs of HBOC patients during the genetic counseling process that could be addressed by digital solutions. Nine semi-structured qualitative interviews were conducted. Overall, the patients appreciated the personal contact with human geneticists as an especially positive factor in the genetic counseling process. However, patients noted the following needs (1) support in the time following genetic counseling, (2) support before genetic counseling by collecting own and familial medical information, (3) Need for contact options to support services, (4) Need for patient-friendly medical information, (5) Wish for administration-related components in a support app. The results will inform the development of a patient-centered mobile support app.

Geographic and sociodemographic aspects may influence the natural history and epidemiology of mucopolysaccharidoses (MPS). The main objective in this work was to evaluate the clinical, molecular, and geographic profile of MPS in a population from Ceará (Northeast Brazil). For this, we have performed a descriptive cross-sectional study based on clinical evaluation, interviews with patients and/or family members, and review of medical records of 76 MPS patients. MPS II was the most common type, with the most affected individuals presenting missense pathogenic variants. Patients with MPS I proved to be the most severe clinical phenotype, presenting the first symptoms (mean: 7.1 months; SD = 4.5) and being diagnosed earlier (2.2 years; SD = 2.1) in comparison with the other types. In addition, we have shown that 13 individuals with MPS VI were born of consanguineous marriages in small, nearby cities, in a place where geographical isolation, consanguinity, and clusters of genetic diseases were previously reported. Ten of these individuals (at least, seven different families) presented a rare pathogenic variant in the ARSB gene, c.1143-8T > G in homozygosity, previously reported only among Iberian and South American patients. The results presented here provide a comprehensive picture of MPS in an important state of the Brazilian Northeast, a region that concentrates many risk factors for rare genetic diseases, such as endogamy, inbreeding, and reproductive isolation. We discuss the possible evolutionary processes and biosocial dynamics that can help to explain this finding in terms of population medical genetics and public health.

This manuscript reviewed the state of the art about the teaching and training of human resources for genetics and genomics in Brazil. We presented the national scenario of teaching genetics in medical undergraduate and other health courses. We discussed the training of medical geneticists through medical residency and addressed the training in genetics of physicians from specialties other than genetics. We examined the training of health professionals specializing in genetics through lato sensu and stricto sensu postgraduate programs and presented the proposals for multi-professional residency in genetic counseling and genetics and genomics that are currently the subject of discussion in the country. Finally, we highlighted the importance of training primary health care professionals concerning genetics and genomics for the effective establishment of a line of care for individuals with genetic disorders in the Brazilian Unified Health System. Therefore, we provided a thorough overview of how genetics is (or is not) incorporated into professional training in a comprehensive public healthcare system such as the Brazilian.

Genetic research can help advance our knowledge of autism and positively impact the progress of care for individuals with autism. Asian American and Pacific Islander (AAPI) and Black participants remain significantly underrepresented in genetic research in autism in the United States, including nationwide, multisite, genetic consortiums like Simons Foundation Powering Autism Research for Knowledge (SPARK). Few studies have explored the unique motivators and barriers that influence participation in genetics research across underrepresented groups with autism and strategies to increase participation. Therefore, the aim of this study was to understand the perspectives of AAPI and Black parents of individuals with autism about participating in genetic research, specifically motivators (e.g., desire to know more about the relationship between autism and genetics) and/or barriers (e.g., mistrust of research staff) that may impact their decision to participate in genetic research. Using a mixed-methods approach, we collected surveys (n = 134) across the United States and conducted three focus groups with parents of individuals with autism (n = 16) who identified as AAPI and Black from two large metropolitan cities. No significant differences were observed in the survey data but findings from the focus groups elucidate shared motivators for participation (e.g., to help advance the autism field for future generations) and nuanced differences in barriers that influence Black and AAPI parents' decision to participate (e.g., different beliefs about the source of autism). Practical suggestions to improve outreach and study engagement in genetic research in autism were identified and discussed.

Familial Hypercholesterolemia (FH) is an inherited disorder that significantly increases an individual's risk of developing premature cardiovascular disease (CVD). Early intervention involving lifestyle modification and medication is crucial in preventing CVD. Prior studies have shown that lipid-lowering therapy in children is safe and effective. Despite FH being a treatable and manageable condition, the condition is still underdiagnosed and undertreated. Universal lipid screening (ULS) in children has been recommended by some medical experts in the United States as a strategy to identify cases of FH and maximize the benefits of early invention. However, lipid screening is not routinely offered in pediatric clinics. This study aimed to explore parental experience with FH diagnosis in their children, identify key facilitators and barriers in children's diagnosis and care, and examine parental perspectives on ULS in children in the United States. A total of fourteen semi-structured interviews were conducted with participants recruited through the Family Heart Foundation. Thematic analysis identified three key themes: role of family history in facilitating child's FH diagnosis, barriers and challenges in post-diagnosis care, and attitudes towards ULS in children. All participants supported ULS in children and emphasized the value of early diagnosis and treatment for FH. However, a lack of guidance or referral after the child's diagnosis was a concern raised by many participants. This underscores the need for accessible and comprehensive care amid ongoing efforts to increase pediatric diagnosis of FH.

Individualised treatment, including genetic services, calls for an increased role of primary healthcare practitioners (pHCPs) in diagnosing and caring for individuals with genetic conditions. PHCPs' genetics knowledge and practices must be current to ensure adequate care. A scoping review was conducted to explore peer-reviewed articles on the knowledge, attitudes, and practices (KAPs) of pHCPs concerning genetics, genetic testing, and genetic services. English-language human genetics/genomics articles published between January 1990 and April 2022 in low- and middle-income countries (LMICs) were included. Twenty-eight articles from 16 LMICs in five World Health Organisation (WHO)-defined regions met the inclusion criteria and showed a steady increase in publications, with varied contributions by region. The Eastern Mediterranean Region (EMR) contributed the most articles (n = 8), while the Western Pacific Region (WPR) had the least (n = 2). Brazil published the most articles (n = 6), while ten countries contributed one article each. Fifteen articles included knowledge, 19 included attitudes towards genetics, and eight included genetic practices. The findings indicate that pHCPs in LMICs lack knowledge of genetics and its applications despite their positive outlook towards genetic services. Barriers such as limited resources, financial constraints, and cultural or religious beliefs hinder access to genetic services. Enhancing pHCPs' genetics education is vital for improving care for those affected by genetic conditions. The scarcity of literature in LMICs emphasises the need for research on educational interventions to improve patient outcomes and family support.

Few policies and little research exist regarding the disclosure of genomic results to research participants in Africa. As understanding participant preferences would be pivotal to the success of the feedback process, this study set out to address this issue by engaging with enrolled participants from an ongoing genomics research project on neurodevelopmental disorders with the aim to assess the anticipated impact of receiving pertinent results and explore the preferences for feedback in a South African context. Twelve semi-structured interviews were conducted with 17 parents of children participating in the research study. Transcribed interview data and observational notes were analysed using thematic analysis and framework matrices. Participants linked their own meaning to the impact of receiving a pertinent result and perceived the information as useful for reasons other than only clinical utility. These included closure, improved management of their child's condition and information regarding recurrence risks. In terms of preferences for feedback, an in-person result delivery session, conducted by a member of the study team or medical professional familiar with their child was preferred. In addition, participants felt a sense of ownership over their blood or their contribution to the research study, finding meaning even in non-pertinent results. These findings provide insight into the type of discussions that may be valuable in enabling the development of best practices and guidelines for the return of individual genetic research results, in a culturally appropriate manner, within South African communities.
