Genes affected
CEACAM7 (HGNC:1819): (CEA cell adhesion molecule 7) This gene encodes a cell surface glycoprotein and member of the carcinoembryonic antigen (CEA) family of proteins. Expression of this gene may be downregulated in colon and rectal cancer. Additionally, lower expression levels of this gene may be predictive of rectal cancer recurrence. 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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 11, 2024The c.751G>A (p.A251T) alteration is located in exon 4 (coding exon 4) of the CEACAM7 gene. This alteration results from a G to A substitution at nucleotide position 751, causing the alanine (A) at amino acid position 251 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
