Simple Virilizing Congenital Adrenal Hyperplasia: A case Report of Sudanese 46, XY DSD male with G293D variant in CYP21A2

Abstract

Congenital Adrenal Hyperplasia (CAH) is a family of inherited disorders that constitute the largest group of Disorders of Sexual Development (DSDs). The classical CAH has two types; the salt-wasting (SW-CAH) and the simple virilizing (SV-CAH). This study is a report of an SV-CAH regarding 46, XY DSD Sudanese male with early signs of puberty at the age of six years. We designed a customized panel that included 48 genes associated with Disorders of Sexual Development (DSDs) and using Next Generation Sequencing (NGS) technology, detected the pathogenic G293D alteration in the CYP21A2 gene. This variant has been reported in the salt-wasting (SW) form of 46, XX CAH.
