Genes affected

TNMD (HGNC:17757): (tenomodulin) This gene encodes a protein that is related to chondromodulin-I, which is a cartilage-specific glycoprotein that functions to stimulate chondrocyte growth and to inhibit tube formation of endothelial cells. This protein is also an angiogenesis inhibitor. Genetic variation in this gene is associated with a risk for type 2 diabetes, central obesity and serum levels of systemic immune mediators in a body size-dependent manner. This gene is also a candidate gene for age-related macular degeneration, though a direct link has yet to be demonstrated. [provided by RefSeq, Sep 2009]

The c.883G>A (p.G295R) alteration is located in exon 7 (coding exon 7) of the TNMD gene. This alteration results from a G to A substitution at nucleotide position 883, causing the glycine (G) at amino acid position 295 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
