Genes affected

CLCA2 (HGNC:2016): (chloride channel accessory 2) This gene encodes a member of the calcium-activated chloride channel regulator (CLCR) family of proteins. Members of this family regulate the transport of chloride across the plasma membrane. The encoded protein is autoproteolytically processed to generate N- and C- terminal fragments. Expression of this gene is upregulated by the tumor suppressor protein p53 in response to DNA damage. In breast cancer, expression of this gene is downregulated and the encoded protein may inhibit migration and invasion while promoting mesenchymal-to-epithelial transition in cancer cell lines.

The c.536A>G (p.N179S) alteration is located in exon 4 (coding exon 4) of the CLCA2 gene. This alteration results from a A to G substitution at nucleotide position 536, causing the asparagine (N) at amino acid position 179 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
