Variant summary

Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM2PP3_Strong

The NM_005125.2(CCS):​c.488G>T​(p.Arg163Leu) variant causes a missense, splice region change. The variant allele was found at a frequency of 0.00000441 in 1,360,044 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 2/3 splice prediction tools predicting alterations to normal splicing. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R163W) has been classified as Likely benign.

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 GeneticsSep 20, 2023The c.488G>T (p.R163L) alteration is located in exon 5 (coding exon 5) of the CCS gene. This alteration results from a G to T substitution at nucleotide position 488, causing the arginine (R) at amino acid position 163 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
