Genes affected

TSPAN31 (HGNC:10539): (tetraspanin 31) The protein encoded by this gene is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. This encoded protein is thought to be involved in growth-related cellular processes. This gene is associated with tumorigenesis and osteosarcoma. [provided by RefSeq, Jul 2008]

The c.512C>G (p.A171G) alteration is located in exon 5 (coding exon 5) of the TSPAN31 gene. This alteration results from a C to G substitution at nucleotide position 512, causing the alanine (A) at amino acid position 171 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
