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 15-48134888-C-G is Pathogenic according to our data. Variant chr15-48134888-C-G is described in ClinVar as [Pathogenic]. Clinvar id is 2431038.Status of the report is criteria_provided_single_submitter, 1 stars.
