GeneDx RCV000656777 SCV000149209 uncertain significance not provided 2014-02-19 criteria provided, single submitter clinical testing BLM has been only recently described in association with cancer predisposition and the risks are not well understood. This variant is denoted BLM c.274A>G at the cDNA level, p.Asn92Asp (N92D) at the protein level, and results in the change of an Asparagine to an Aspartic Acid (AAT>GAT). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. BLM Asn92Asp was not observed at significant allele frequency in the NHLBI Exome Sequencing Project. This variant is a semi-conservative substitution in which a neutral polar amino acid is replaced with a negative polar one, altering a position that is only moderately conserved throughout evolution and is not located in a known functional domain. In silico analyses predict this variant to have a benign effect on protein structure and function. On a molecular level, the impact of this missense variant on protein structure and function is not known and thus we consider this to be a variant of uncertain significance. Furthermore, based on the currently available information, cancer risks associated with this variant, and the BLM gene, remain unclear.
