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]

This sequence change creates a premature translational stop signal (p.Leu214Argfs*12) 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). This variant is present in population databases (rs772398324, gnomAD 0.009%). This premature translational stop signal has been observed in individual(s) with clinical features of oculocutaneous albinism (PMID: 23985994). ClinVar contains an entry for this variant (Variation ID: 440483). For these reasons, this variant has been classified as Pathogenic. -

The SLC24A5 c.641delT variant is predicted to result in a frameshift and premature protein termination (p.Leu214Argfs*12). This variant has been reported in the homozygous state in individuals with oculocutaneous albinism (Morice-Picard et al. 2014. PubMed ID: 23985994). This variant is reported in 0.0087% of alleles in individuals of Latino descent in gnomAD. Frameshift variants in SLC24A5 are expected to be pathogenic. This variant is interpreted as pathogenic. -
