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]

Familial thoracic aortic aneurysm and aortic dissection Pathogenic:2
Pathogenic, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2023The p.Y216* pathogenic mutation (also known as c.648C>G), located in coding exon 2 of the SLC2A10 gene, results from a C to G substitution at nucleotide position 648. This changes the amino acid from a tyrosine to a stop codon within coding exon 2. This variant has been detected in an individual with aortic aneurysm who also had a variant in the MYH11 gene (Weerakkody R et al. Genet Med, 2018 Nov;20:1414-1422). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. -

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 19, 2024This sequence change creates a premature translational stop signal (p.Tyr216*) in the SLC2A10 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SLC2A10 are known to be pathogenic (PMID: 17935213, 22488877, 23494979). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SLC2A10-related conditions. ClinVar contains an entry for this variant (Variation ID: 467819). For these reasons, this variant has been classified as Pathogenic. -
