Genes affected

SLC2A8 (HGNC:13812): (solute carrier family 2 member 8) This gene belongs to the solute carrier 2A family, which includes intracellular glucose transporters. Based on sequence comparison, the glucose transporters are grouped into three classes and this gene is a member of class II. The encoded protein, like other members of the family, contains several conserved residues and motifs and 12 transmembrane domains with both amino and carboxyl ends being on the cytosolic side of the membrane. Alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, Nov 2012]

The c.277C>A (p.R93S) alteration is located in exon 3 (coding exon 3) of the SLC2A8 gene. This alteration results from a C to A substitution at nucleotide position 277, causing the arginine (R) at amino acid position 93 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
