Genes affected

DMRT1 (HGNC:2934): (doublesex and mab-3 related transcription factor 1) This gene is found in a cluster with two other members of the gene family, having in common a zinc finger-like DNA-binding motif (DM domain). The DM domain is an ancient, conserved component of the vertebrate sex-determining pathway that is also a key regulator of male development in flies and nematodes. This gene exhibits a gonad-specific and sexually dimorphic expression pattern. Defective testicular development and XY feminization occur when this gene is hemizygous. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.68C>T (p.P23L) alteration is located in exon 1 (coding exon 1) of the DMRT1 gene. This alteration results from a C to T substitution at nucleotide position 68, causing the proline (P) at amino acid position 23 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
