GeneDx RCV000044913 SCV000210386 likely benign not specified 2017-04-06 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.

Illumina Clinical Services Laboratory,Illumina RCV000406166 SCV000383740 likely benign Fanconi anemia, complementation group D1 2019-03-19 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). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.

A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.

Integrated Genetics/Laboratory Corporation of America RCV000034454 SCV000694965 likely benign not provided 2016-12-01 criteria provided, single submitter clinical testing Variant summary: The BRCA2 c.6325G>A (p.Val2109Ile) variant involves the alteration of a non-conserved nucleotide. 4/4 in silico tools predict a benign outcome for this variant (SNPs&GO not captured due to low reliability index). This variant was found in 38/122036 control chromosomes, predominantly observed in the East Asian subpopulation at a frequency of 0.0038354 (33/8604). This frequency is about 5 times the estimated maximal expected allele frequency of a pathogenic BRCA2 variant (0.0007503), suggesting this is likely a benign polymorphism found primarily in the populations of East Asian origin. The variant has been reported in numerous affected individuals in the literature, mostly of Asian origin, without strong evidence for causality. BIC reports the variant in 2 individuals who also carry pathogenic variants (BRCA1 c.4163_4164insA; BRCA2 c.9076C>T), also supportive of a benign outcome. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as likely benign/benign, although some classify it as a VUS. Taken together, this variant is classified likley benign.
