Description

The CYP21A2 c.1024C>T variant is predicted to result in the amino acid substitution p.Arg342Trp. Also known as R341W in the literature, this variant has been associated with autosomal recessive non-classic congenital adrenal hyperplasia (CAH) likely due to affected strength of P450 oxidoreductase (POR) interactions (see for example, Liu et al. 2018. PubMed ID: 29328376; Haider et al. 2013. PubMed ID: 23359706; Barbaro et al. 2015. PubMed ID: 24953648). This variant is interpreted as pathogenic.
