Genes affected

SLC24A5 (HGNC:20611): (solute carrier family 24 member 5) This gene is a member of the potassium-dependent sodium/calcium exchanger family and encodes an intracellular membrane protein with 2 large hydrophilic loops and 2 sets of multiple transmembrane-spanning segments. Sequence variation in this gene has been associated with differences in skin pigmentation. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. There are 16 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 15-48121139-TG-T is Pathogenic according to our data. Variant chr15-48121139-TG-T is described in ClinVar as [Pathogenic]. Clinvar id is 2116280.Status of the report is criteria_provided_single_submitter, 1 stars.

For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with SLC24A5-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Gln34Asnfs*37) in the SLC24A5 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SLC24A5 are known to be pathogenic (PMID: 23985994, 26686029). -
