Genes affected

SLC2A12 (HGNC:18067): (solute carrier family 2 member 12) SLC2A12 belongs to a family of transporters that catalyze the uptake of sugars through facilitated diffusion (Rogers et al., 2002). This family of transporters show conservation of 12 transmembrane helices as well as functionally significant amino acid residues (Joost and Thorens, 2001 [PubMed 11780753]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.1481G>A (p.G494E) alteration is located in exon 3 (coding exon 3) of the SLC2A12 gene. This alteration results from a G to A substitution at nucleotide position 1481, causing the glycine (G) at amino acid position 494 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
