Background and Aim: The SF-1/NR5A1 variant c.437G>C/p.Gly146Ala is common among individuals with disorders/differences of sex development (DSD). It has been considered a polymorphism due to its high allele frequency in the control population (23.5%, gnomAD) and its lack of negative effect in cell-based studies. However, its possible role as a disease modifier is still unclear given that oligogenic inheritance has been described in patients with SF1...
