RCV001913643 | SCV002186664 | uncertain significance | Bloom syndrome | 2021-08-25 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (ExAC no frequency). This sequence change replaces lysine with asparagine at codon 188 of the BLM protein (p.Lys188Asn). The lysine residue is weakly conserved and there is a moderate physicochemical difference between lysine and asparagine. This variant has not been reported in the literature in individuals affected with BLM-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
