Invitae | RCV001216851 | SCV001388667 | uncertain significance | Baller-Gerold syndrome | 2019-04-24 | criteria provided, single submitter | clinical testing | This sequence change replaces histidine with glutamine at codon 675 of the RECQL4 protein (p.His675Gln). The histidine residue is highly conserved and there is a small physicochemical difference between histidine and glutamine. 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with RECQL4-related conditions. This variant is not present in population databases (ExAC no frequency). |
