Collection Method: clinical testing

The c.82A>G (p.M28V) alteration is located in exon 3 (coding exon 3) of the COMMD6 gene. This alteration results from a A to G substitution at nucleotide position 82, causing the methionine (M) at amino acid position 28 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
