Collection Method:clinical testing

The c.23A>C (p.E8A) alteration is located in exon 1 (coding exon 1) of the COMMD2 gene. This alteration results from a A to C substitution at nucleotide position 23, causing the glutamic acid (E) at amino acid position 8 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
