GeneDx RCV000045856 SCV000210553 likely benign not specified 2017-08-07 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 1.7e-05 in 229618 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.956A>G has been reported in the literature in one patient with pancreatic cancer (Grant_2015) and in at least one individual affected with unilateral breast cancer (Borg_2010, Capanu_2010) without strong evidence for causality. These reports do not provide unequivocal conclusions about association of the variant with Hereditary Breast and Ovarian Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Six other clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Multiple laboratories reported the variant with conflicting assessments: three cited the variant as uncertain significance, one cited the variant as likely benign, and one cited the variant as benign. Based on the evidence outlined above, the variant was classified as uncertain significance.

Illumina Clinical Services Laboratory,Illumina RCV001109313 SCV001266635 uncertain significance Fanconi anemia, complementation group D1 2018-01-15 criteria provided, single submitter 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, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
