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 Likely_benign. Variant got -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.55).
• BP7: Synonymous conserved (PhyloP=0.066 with no splicing effect.
