Genes affected

CD82 (HGNC:6210): (CD82 molecule) This metastasis suppressor gene product is a membrane glycoprotein that is a member of the transmembrane 4 superfamily. Expression of this gene has been shown to be downregulated in tumor progression of human cancers and can be activated by p53 through a consensus binding sequence in the promoter. Its expression and that of p53 are strongly correlated, and the loss of expression of these two proteins is associated with poor survival for prostate cancer patients. Two alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.95T>C (p.V32A) alteration is located in exon 4 (coding exon 2) of the CD82 gene. This alteration results from a T to C substitution at nucleotide position 95, causing the valine (V) at amino acid position 32 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
