Genes affected

DMRT3 (HGNC:13909): (doublesex and mab-3 related transcription factor 3) Enables sequence-specific double-stranded DNA binding activity. Predicted to be involved in male sex differentiation and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including adult walking behavior; transmission of nerve impulse; and ventral spinal cord interneuron specification. Predicted to be part of chromatin. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

The c.523A>G (p.T175A) alteration is located in exon 2 (coding exon 2) of the DMRT3 gene. This alteration results from a A to G substitution at nucleotide position 523, causing the threonine (T) at amino acid position 175 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
