GeneDx RCV000034421 SCV000292853 uncertain significance not provided 2017-07-20 criteria provided, single submitter clinical testing This variant is denoted APC c.7717A>G at the cDNA level, p.Ile2573Val (I2573V) at the protein level, and results in the change of an Isoleucine to a Valine (ATT>GTT). Azzopardi et al. (2008) identified this variant in 1/691 individuals with a history of multiple colorectal adenomas and 0/969 control subjects, while Johnston et al. (2012) reported it in 1/571 individuals with atherosclerosis, with no specific information about cancer history. APC Ile2573Val was observed at an allele frequency of 0.03% (18/66,664) in individuals of European (Non-Finnish) ancestry in large population cohorts (Lek 2016). Since Isoleucine and Valine share similar properties, this is considered a conservative amino acid substitution. APC Ile2573Val occurs at a position where amino acids with properties similar to Isoleucine are tolerated across species and is located in the EB1 binding domain (Azzopardi 2008). In silico analyses are inconsistent regarding the effect this variant may have on protein structure and function. Based on currently available evidence, it is unclear whether APC Ile2573Val is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.

Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000236063 SCV000538305 uncertain significance not specified 2017-01-24 criteria provided, single submitter clinical testing Variant identified in a genome or exome case(s) and assessed due to predicted null impact of the variant or pathogenic assertions in the literature or databases. 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.
