Genes affected
SLC3A1 (HGNC:11025): (solute carrier family 3 member 1) This gene encodes a type II membrane glycoprotein which is one of the components of the renal amino acid transporter which transports neutral and basic amino acids in the renal tubule and intestinal tract. Mutations and deletions in this gene are associated with cystinuria. Alternatively spliced transcript variants have been described, but their biological validity has not been determined.

Submissions by phenotype

Cystinuria Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeJul 29, 2022This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 34 of the SLC3A1 protein (p.Thr34Ala). This variant is present in population databases (rs748553507, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with SLC3A1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest 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. -
