Genes affected

SLC5A1 (HGNC:11036): (solute carrier family 5 member 1) This gene encodes a member of the sodium-dependent glucose transporter (SGLT) family. The encoded integral membrane protein is the primary mediator of dietary glucose and galactose uptake from the intestinal lumen. Mutations in this gene have been associated with glucose-galactose malabsorption. Multiple transcript variants encoding different isoforms have been found for this gene.

This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 30 of the SLC5A1 protein (p.Ser30Phe). This variant is present in population databases (rs201689857, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with SLC5A1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1397738). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). 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. -
