Disclaimer: This variant has not undergone full assessment. The following are preliminary notes: This variant has been reported in 2 individuals with colorectal adenomas and 1 individual with no cancer. The variant has a Max MAF of 0.03% in ExAC (18 alleles) and 0.02% in gnomAD (21 alleles). Frequency too high for disease? It is classified with 2 stars in ClinVar as VUS by Invitae, Ambry, GeneDx, CSER_CC_NCGL, and Biesecker lab. 10 non-mammals have a Val at this position.

RCV000122803	SCV004018795	likely benign	Familial adenomatous polyposis 1	2023-02-22	criteria provided, single submitter	clinical testing	This variant is considered likely benign. This variant is strongly associated with less severe personal and family histories of cancer, typical for individuals without pathogenic variants in this gene [PMID: 25085752].
Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV000236063	SCV004099683	likely benign	not specified	2023-09-11	criteria provided, single submitter	clinical testing	Variant summary: APC c.7717A>G (p.Ile2573Val) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 8.8e-05 in 250818 control chromosomes, predominantly at a frequency of 0.00018 within the Non-Finnish European subpopulation in the gnomAD database. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 2.5 fold of the estimated maximal expected allele frequency for a pathogenic variant in APC causing Familial Adenomatous Polyposis phenotype (7.1e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Non-Finnish European origin. c.7717A>G has been reported in the literature in and individual affected with Colorectal Adenomas (Azzopard_2008) without evidence for causality. This report does not provide unequivocal conclusions about association of the variant with Familial Adenomatous Polyposis. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 18199528). Twelve submitters have cited clinical-significance assessments for this variant to ClinVar after 2014 and classified as likely benign (n=6) and VUS (n=6). Based on the evidence outlined above, the variant was classified as likely benign.
