Genes affected
SLC7A14 (HGNC:29326): (solute carrier family 7 member 14) This gene is predicted to encode a glycosylated, cationic amino acid transporter protein with 14 transmembrane domains. This gene is primarily expressed in skin fibroblasts, neural tissue, and primary endothelial cells and its protein is predicted to mediate lysosomal uptake of cationic amino acids. Mutations in this gene are associated with autosomal recessive retinitis pigmentosa. In mice, this gene is expressed in the photoreceptor layer of the retina where its expression increases over the course of retinal development and persists in the mature retina.

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpSep 08, 2023This variant has not been reported in the literature in individuals affected with SLC7A14-related conditions. This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 769 of the SLC7A14 protein (p.Ser769Cys). This variant is present in population databases (rs751070707, gnomAD 0.007%). ClinVar contains an entry for this variant (Variation ID: 1027117). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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. -
