Equity-focused implementation to enhance access to rare disease genomic research and understand diverse perspectives.

purposeRare disease genomic research suffers from a lack of diverse participation. We therefore implemented and evaluated a multi-faceted intervention to support recruitment of populations previously underrepresented by race, ethnicity, primary language, household income, education level, or rural residence to the Rare Genomes Project.

methodsFor a prospective cohort, we tracked completion of our enrollment processes supported by interventions including clinician engagement, language support, proactive and flexible participant contact, and use of mobile phlebotomy. Participants were offered a survey upon enrollment to assess values and priorities.

resultsIn total, 161 of 195 (83%) participants completed enrollment. High-yield interventions included clinician referral forms and increased staff assistance. Genome sequencing data have been generated for 133 participants, with a diagnosis found for 17 (13%) and candidate for 23 (17%) thus far. Most diagnosed participants (13/17, 76%) benefited from clinician rather than self-referral. Perceived importance of a genetic diagnosis was ranked very/extremely high for 81 of 96 (84%) of participants. Spanish primary language was associated with higher perceived importance and high income with lower perceived importance, although only income remained significant in a multivariable model.

conclusionOverall, our equity-focused initiative enabled enrollment of participants from populations previously underrepresented in rare disease genomic research and offers insight into potential motivators.
