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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 18, 2024The c.775A>G (p.I259V) alteration is located in exon 8 (coding exon 8) of the CCS gene. This alteration results from a A to G substitution at nucleotide position 775, causing the isoleucine (I) at amino acid position 259 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
