Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBS1BS2

The NM_000038.6(APC):​c.7504G>A​(p.Gly2502Ser) variant causes a missense change. The variant allele was found at a frequency of 0.0199 in 1,613,962 control chromosomes in the GnomAD database, including 412 homozygotes. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G2502D) has been classified as Uncertain significance.

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.

Significance:Benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Significance:Benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

Review Status:no assertion criteria provided
Collection Method:clinical testing

The p.Gly2502Ser variant was previously identified in the literature in 138 of 6866 proband chromosomes (frequency 0.020) from individuals with adenoma or colorectal cancer and in 157 of 8192 control chromosomes (frequency 0.019) from healthy individuals (Cleary 2008, Hadjisavvas 2006, Miyoshi 1992, Scott 2004, Tranah 2005, Wong 2010, Zhou 2004). This variant was also identified in the dbSNP (ID#rs2229995), HGMD, and LOVD databases, and was reported in several populations including the ESP Project with a frequency of 0.020 in European American alleles, the 1000 Genomes Project with a frequency of 0.010, and HapMap-CEU with a frequency of 0.032. The p.Gly2502 residue is not conserved through evolution and the variant (Ser) is found at this position in chicken and fruitfly, increasing the likelihood that this is a benign variant. In addition, Tranah (2005) found that this variant was not associated with risk of colorectal cancer or adenoma in men and women, and Zhou (2004) did not observe segregation of this variant with disease. In summary, based on the above information, this variant meets our laboratory's criteria to be classified as benign. -
