GeneDx RCV000193294 SCV000167196 benign not specified 2013-10-24 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.

Integrated Genetics/Laboratory Corporation of America RCV000588309 SCV000694479 benign not provided 2016-06-12 criteria provided, single submitter clinical testing Variant summary: The c.4076+4T>G in a BLM gene is an intronic variant that alters a non-conserved nucleotide. 5/5 in silico tools via Alamut predict this variant to not affect normal splicing, however these predictions have yet to be confirmed by functional assay. The variant is present in control dataset of ExAC at a frequency of 0.0038 (458/119942 chrs tested, including 3 homozygous occurrences) which exceeds the estimated maximum allele frequency for a pathogenic allele in this gene (0.0035), suggesting that this variant is a likely polymorphism. The variant has been reported in affected with breast cancer in literature (Thompson_2012) without strong evidence of causality. Multiple clinical laboratories have classified the variant as "Benign. Taken together, the variant is classified as Benign.
