Genes affected

SRD5A2 (HGNC:11285): (steroid 5 alpha-reductase 2) This gene encodes a microsomal protein expressed at high levels in androgen-sensitive tissues such as the prostate. The encoded protein is active at acidic pH and is sensitive to the 4-azasteroid inhibitor finasteride. Deficiencies in this gene can result in male pseudohermaphroditism, specifically pseudovaginal perineoscrotal hypospadias (PPSH). [provided by RefSeq, Jul 2008]

Identified in an individual from a 5-alpha-reductase deficiency cohort, however, it is unknown if this was seen in the homozygous state or with a second SRD5A2 variant (PMID: 32380235); The majority of missense variants in this gene are considered pathogenic (HGMD); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; This variant is associated with the following publications: (PMID: 21604088, 32380235, 33469028, 10718838) -
