Improving access to exome sequencing in a medically underserved population through the Texome Project.

PURPOSE: Genomic medicine can end diagnostic odysseys for patients with complex phenotypes; however, limitations in insurance coverage and other systemic barriers preclude individuals from accessing comprehensive genetics evaluation and testing. METHODS: The Texome Project is a 4-year study that reduces barriers to genomic testing for individuals from underserved and underrepresented populations. Participants with undiagnosed, rare diseases who have financial barriers to obtaining exome sequencing (ES) clinically are enrolled in the Texome Project. RESULTS: We highlight the Texome Project process and describe the outcomes of the first 60 ES results for study participants. Participants received a genetic evaluation, ES, and return of results at no cost. We summarize the psychosocial or medical implications of these genetic diagnoses. Thus far, ES provided molecular diagnoses for 18 out of 60 (30%) of Texome participants. Plus, in 11 out of 60 (18%) participants, a partial or probable diagnosis was identified. Overall, 5 participants had a change in medical management. CONCLUSION: To date, the Texome Project has recruited a racially, ethnically, and socioeconomically diverse cohort. The diagnostic rate and medical impact in this cohort support the need for expanded access to genetic testing and services. The Texome Project will continue reducing barriers to genomic care throughout the future study years.

Improved health care transition for young adults with developmental disabilities referred from designated transition clinics.

PURPOSE: Young adults with intellectual/developmental disabilities (YAIDD) are a vulnerable population during HCT due to their complex care coordination and adaptive needs, yet factors associated with transition preparedness are not well defined. We aimed to determine factors associated with health care transition (HCT) preparation satisfaction for YAIDD establishing care with an adult medical home. DESIGN AND METHODS: 408 YAIDD or their families completed the HCT Feedback Survey 2.0 upon establishing adult care. Logistic regression models were used to determine associations between a composite of six HCT Feedback Survey questions that most correlated with the 2019 National Survey of Children's Health transition questions. RESULTS: YADD who had HCT preparation visits with a designated HCT clinic were 9 times more likely to have met all six composite HCT criteria after controlling for the number of technologies required and race/ethnicity (adj OR 9.04, 95% CI: 4.35, 18.76) compared to those referred from the community. Compared to patients who were referred from the community, the odds of feeling very prepared versus somewhat or not prepared were 3.7 times higher (adj OR 3.73, 95% CI: 1.90, 7.32) among patients referred from a designated HCT program. CONCLUSIONS: YAIDD who participated in a structured HCT program prior to transfer to adult care experienced higher transition preparation satisfaction. PRACTICAL IMPLICATIONS: A structured HCT clinic model to prepare adolescents with DD for transition to adult care may improve HCT preparation satisfaction for this population.
