The c.1468G>A (p.G490S) alteration is located in exon 3 (coding exon 2) of the DMRTA2 gene. This alteration results from a G to A substitution at nucleotide position 1468, causing the glycine (G) at amino acid position 490 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
