Genes affected

APC (HGNC:583): (APC regulator of WNT signaling pathway) This gene encodes a tumor suppressor protein that acts as an antagonist of the Wnt signaling pathway. It is also involved in other processes including cell migration and adhesion, transcriptional activation, and apoptosis. Defects in this gene cause familial adenomatous polyposis (FAP), an autosomal dominant pre-malignant disease that usually progresses to malignancy. Mutations in the APC gene have been found to occur in most colorectal cancers, where disease-associated mutations tend to be clustered in a small region designated the mutation cluster region (MCR) and result in a truncated protein product.

Uncertain significance, criteria provided, single submitter	clinical testing	Foundation for Research in Genetics and Endocrinology, FRIGE's Institute of Human Genetics	Apr 07, 2023	A heterozygous missense substitution (p.Ser843Gly) lies in exon 16 of the APC gene and alters a highly conserved residue in the protein. In silico prediction of the variant are damaging by LRT, Mutation Taster and SIFT. In summary, the variant meets our criteria to be classified as a variant of uncertain significance. -
