Genes affected

CD5 (HGNC:1685): (CD5 molecule) This gene encodes a member of the scavenger receptor cysteine-rich (SRCR) superfamily. Members of this family are secreted or membrane-anchored proteins mainly found in cells associated with the immune system. This protein is a type-I transmembrane glycoprotein found on the surface of thymocytes, T lymphocytes and a subset of B lymphocytes. The encoded protein contains three SRCR domains and may act as a receptor to regulate T-cell proliferation. Alternative splicing results in multiple transcript variants encoding different isoforms.

Collection Method: clinical testing

The c.173T>A (p.M58K) alteration is located in exon 3 (coding exon 3) of the CD5 gene. This alteration results from a T to A substitution at nucleotide position 173, causing the methionine (M) at amino acid position 58 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
