Genes affected

SLC2A10 (HGNC:13444): (solute carrier family 2 member 10) This gene encodes a member of the class III facilitative glucose transporter family. The encoded protein plays a role in regulation of glucose homeostasis. Mutations in this gene have been associated with arterial tortuosity syndrome.[provided by RefSeq, Dec 2009]

This sequence change replaces arginine with histidine at codon 296 of the SLC2A10 protein (p.Arg296His). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and histidine. This variant is present in population databases (rs558025597, ExAC 0.01%). This variant has not been reported in the literature in individuals affected with SLC2A10-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 disruptive. 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. -
