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]

Submissions by phenotype

Familial thoracic aortic aneurysm and aortic dissection Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 18, 2020The p.L201F variant (also known as c.601C>T), located in coding exon 2 of the SLC2A10 gene, results from a C to T substitution at nucleotide position 601. The leucine at codon 201 is replaced by phenylalanine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
Arterial tortuosity syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpSep 02, 2021This sequence change replaces leucine with phenylalanine at codon 201 of the SLC2A10 protein (p.Leu201Phe). The leucine residue is highly conserved and there is a small physicochemical difference between leucine and phenylalanine. This variant is present in population databases (rs199861432, ExAC 0.03%). 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; 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. -
