Collection Method: clinical testing

The c.282G>C (p.Q94H) alteration is located in exon 3 (coding exon 2) of the DMRTC2 gene. This alteration results from a G to C substitution at nucleotide position 282, causing the glutamine (Q) at amino acid position 94 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
