Genes affected
CEACAM5 (HGNC:1817): (CEA cell adhesion molecule 5) This gene encodes a cell surface glycoprotein that represents the founding member of the carcinoembryonic antigen (CEA) family of proteins. The encoded protein is used as a clinical biomarker for gastrointestinal cancers and may promote tumor development through its role as a cell adhesion molecule. Additionally, the encoded protein may regulate differentiation, apoptosis, and cell polarity. This gene is present in a CEA family gene cluster on chromosome 19. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2015]

The c.227A>C (p.N76T) alteration is located in exon 2 (coding exon 2) of the CEACAM5 gene. This alteration results from a A to C substitution at nucleotide position 227, causing the asparagine (N) at amino acid position 76 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
