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]

MYEF2 (HGNC:17940): (myelin expression factor 2) Enables RNA binding activity. Involved in myotube differentiation and neuron differentiation. Located in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 15-48134912-TCAGAGACTGTG-T is Pathogenic according to our data. Variant chr15-48134912-TCAGAGACTGTG-T is described in ClinVar as [Pathogenic]. Clinvar id is 1939262.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.Arg174Serfs*5) 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). -
