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]

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change creates a premature translational stop signal (p.Tyr139*) 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 present in population databases (rs572620317, gnomAD 0.002%). This premature translational stop signal has been observed in individual(s) with arterial tortuosity syndrome (PMID: 23494979). ClinVar contains an entry for this variant (Variation ID: 161095). For these reasons, this variant has been classified as Pathogenic. -
