Genes affected

SLC2A3 (HGNC:11007): (solute carrier family 2 member 3) Enables dehydroascorbic acid transmembrane transporter activity; glucose binding activity; and glucose transmembrane transporter activity. Involved in glucose import across plasma membrane and transport across blood-brain barrier. Is integral component of plasma membrane. Biomarker of Alzheimer's disease; acanthosis nigricans; diabetes mellitus; and type 2 diabetes mellitus. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Oct 26, 2022

The c.843G>T (p.Q281H) alteration is located in exon 6 (coding exon 6) of the SLC2A3 gene. This alteration results from a G to T substitution at nucleotide position 843, causing the glutamine (Q) at amino acid position 281 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
