Invitae RCV000232622 SCV000288684 likely benign Oligodontia-cancer predisposition syndrome 2024-01-29 criteria provided, single submitter clinical testing
Illumina Laboratory Services, Illumina RCV000232622 SCV000405688 likely benign Oligodontia-cancer predisposition syndrome 2017-04-27 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.

Ambry Genetics RCV001013812 SCV001174443 likely benign Hereditary cancer-predisposing syndrome 2019-10-03 criteria provided, single submitter clinical testing This alteration is classified as likely benign based on a combination of the following: 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.
Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV002229662 SCV002511696 likely benign not specified 2022-04-28 criteria provided, single submitter clinical testing Variant summary: AXIN2 c.1975C>T (p.Arg659Trp) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00027 in 245028 control chromosomes. The observed variant frequency is approximately 2 fold of the estimated maximal expected allele frequency for a pathogenic variant in AXIN2 causing Colorectal Cancer phenotype (0.00014), strongly suggesting that the variant is benign. c.1975C>T has been reported in the literature in at least one individual affected with Colorectal Cancer. These reports do not provide unequivocal conclusions about association of the variant with Colorectal Cancer. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as likely benign. Based on the evidence outlined above, the variant was classified as likely benign.
