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]

SLC2A10 Gene-Disease associations (from GenCC):

• arterial tortuosity syndrome

  Inheritance: AR Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: Genomics England PanelApp, PanelApp Australia, Orphanet, Labcorp Genetics (formerly Invitae), Ambry Genetics, ClinGen, G2P

ACMG classification

Our verdict: Uncertain_significance. The variant received 3 ACMG points.
