In a national multicentre study of 95 children with PAI of unknown aetiology (non‐CAH, nonautoimmune, nonmetabolic) in Turkey, a genetic diagnosis was made in almost 90% of individuals, with variants in just 10 genes (eg MC2R, NR0B1 (DAX‐1), STAR, CYP11A1, MRAP, NNT, ABCD1, NR5A1, AAAS, SGPL1).37 Key founder effects and geographical hot spots were seen, such as a recurrent MRAP slice variant in Western Turkey and partial loss‐of‐function variant in CYP11A1 in Central regions. Here, CYP11A1 is linked to congenital adrenal hyperplasia.
