Collection Method: clinical testing

The c.412G>A (p.A138T) alteration is located in exon 1 (coding exon 1) of the DMRTA1 gene. This alteration results from a G to A substitution at nucleotide position 412, causing the alanine (A) at amino acid position 138 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
