Genes affected

CCS (HGNC:1613): (copper chaperone for superoxide dismutase) Copper chaperone for superoxide dismutase specifically delivers Cu to copper/zinc superoxide dismutase and may activate copper/zinc superoxide dismutase through direct insertion of the Cu cofactor. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.410T>C (p.L137P) alteration is located in exon 4 (coding exon 4) of the CCS gene. This alteration results from a T to C substitution at nucleotide position 410, causing the leucine (L) at amino acid position 137 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
