Ambry Genetics RCV000166674 SCV000217482 uncertain significance Hereditary cancer-predisposing syndrome 2023-06-19 criteria provided, single submitter clinical testing The c.6811_6813delCCT variant (also known as p.P2271del) is located in coding exon 15 of the APC gene. This variant results from an in-frame CCT deletion at nucleotide positions 6811 to 6813. This results in the in-frame deletion of a proline at codon 2271. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be neutral by in silico analysis (Choi Y et al. PLoS ONE. 2012; 7(10):e46688). Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
Invitae RCV003650433 SCV000552530 uncertain significance Familial adenomatous polyposis 1 2024-01-12 criteria provided, single submitter clinical testing This variant, c.6811_6813del, results in the deletion of 1 amino acid(s) of the APC protein (p.Pro2271del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs761567827, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with APC-related conditions. ClinVar contains an entry for this variant (Variation ID: 186999). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
GeneDx RCV000485036 SCV000564581 uncertain significance not provided 2019-11-05 criteria provided, single submitter clinical testing In-frame deletion of 1 amino acid in a non-repeat region; Has not been previously published as pathogenic or benign to our knowledge; In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function
Color Diagnostics, LLC DBA Color Health RCV000166674 SCV001353124 uncertain significance Hereditary cancer-predisposing syndrome 2023-03-06 criteria provided, single submitter clinical testing This variant is located in the APC protein. To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with APC-related disorders in the literature. This variant has been identified in 3/251010 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.
