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]

SLC24A5 links:

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]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SLC24A5 protein function. 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 replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 166 of the SLC24A5 protein (p.Thr166Ile). -
