Genes affected

SLC2A4 (HGNC:11009): (solute carrier family 2 member 4) This gene is a member of the solute carrier family 2 (facilitated glucose transporter) family and encodes a protein that functions as an insulin-regulated facilitative glucose transporter. In the absence of insulin, this integral membrane protein is sequestered within the cells of muscle and adipose tissue. Within minutes of insulin stimulation, the protein moves to the cell surface and begins to transport glucose across the cell membrane. Mutations in this gene have been associated with noninsulin-dependent diabetes mellitus (NIDDM). [provided by RefSeq, Jul 2008]

The c.356C>T (p.A119V) alteration is located in exon 4 (coding exon 4) of the SLC2A4 gene. This alteration results from a C to T substitution at nucleotide position 356, causing the alanine (A) at amino acid position 119 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
