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]

Ambry Genetics

Oct 09, 2024

The c.124A>G (p.T42A) alteration is located in exon 2 (coding exon 2) of the TNMD gene. This alteration results from a A to G substitution at nucleotide position 124, causing the threonine (T) at amino acid position 42 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
