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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2023The c.1459G>A (p.E487K) alteration is located in exon 10 (coding exon 10) of the SLC2A3 gene. This alteration results from a G to A substitution at nucleotide position 1459, causing the glutamic acid (E) at amino acid position 487 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
