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.

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -11 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.42).
BP6
Variant 5-112707514-A-G is Benign according to our data. Variant chr5-112707514-A-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 469859.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1}.
BS1
Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.000716 (109/152196) while in subpopulation AMR AF= 0.0068 (104/15290). AF 95% confidence interval is 0.00574. There are 1 homozygotes in gnomad4. There are 78 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
BS2
High AC in GnomAd4 at 109 AD gene.
