Abstract
Background: Steroidogenic Factor 1/Nuclear Receptor Subfamily 5 Group A Member 1 (SF-1/NR5A1) is critical for the development and function of sex organs, influencing steroidogenesis and reproduction. While rare deleterious NR5A1/SF-1 variants have been identified in individuals with various differences of sex development (DSD), primary ovarian insufficiency, and infertility, their impact on the general population remains unclear.</p>
Methods: We analyzed health records and exome sequencing data from up to 420 162 individuals (227 858 women) from the UK Biobank study to assess the impact of rare (frequency < 0.1%) predicted deleterious NR5A1/SF-1 variants on age at menopause and 26 other traits.</p>
Results: No carriers of rare protein truncating variants in NR5A1/SF-1 were identified. We found that the previously reported association of rare deleterious missense NR5A1/SF-1 variants with earlier age at menopause is driven by variants in the DNA binding domain (DBD) and ligand binding domain (LBD) (combined test: beta = -2.36 years/allele, [95% CI: 3.21, -1.51], N = 107 carriers, P = 4.6 × 10-8). Carriers also had a higher risk of adult obesity (OR = 1.061, [95% CI: 1.003, 1.104], N = 344, P = .015), particularly among women (OR = 1.095 [95% CI: 1.034, 1.163, P = 3.87 × 10-3], N = 176), but not men (OR = 1.019, [95% CI: 0.955, 1.088], P = .57, N = 168).</p>
Conclusion: Deleterious missense variants in the DBD and LBD likely disrupt NR5A1/SF-1 function. This study broadens the relevance of deleterious NR5A1/SF-1 variants beyond rare DSDs, suggesting the need for extended phenotyping and monitoring of affected individuals.</p>
