Background: Mutations in CYP21A2 are the most common cause of congenital adrenal hyperplasia (CAH). Even though disease linked mutations are rarely classified as founder, in this study, we describe a novel founder mutation, c.2T>C (p.M1?), inactivating the translation initiation codon.Objective and Hypotheses: We aimed to investigate genotype–phenotype correlation and population based origin of this novel mutation in CAH patients with 2...
