Genes affected

CEACAM3 (HGNC:1815): (CEA cell adhesion molecule 3) This gene encodes a member of the family of carcinoembryonic antigen-related cell adhesion molecules (CEACAMs), which are used by several bacterial pathogens to bind and invade host cells. The encoded transmembrane protein directs phagocytosis of several bacterial species that is dependent on the small GTPase Rac. It is thought to serve an important role in controlling human-specific pathogens by the innate immune system. Alternatively spliced transcript variants have been described.

Collection Method: clinical testing

The c.304T>C (p.Y102H) alteration is located in exon 2 (coding exon 2) of the CEACAM3 gene. This alteration results from a T to C substitution at nucleotide position 304, causing the tyrosine (Y) at amino acid position 102 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
