Collection Method:clinical testing

The c.322T>C (p.C108R) alteration is located in exon 2 (coding exon 2) of the VMAC gene. This alteration results from a T to C substitution at nucleotide position 322, causing the cysteine (C) at amino acid position 108 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
