Invitae RCV000228236 SCV000288179 uncertain significance Baller-Gerold syndrome 2018-08-02 criteria provided, single submitter clinical testing This sequence change replaces threonine with methionine at codon 52 of the RECQL4 protein (p.Thr52Met). The threonine residue is weakly conserved and there is a moderate physicochemical difference between threonine and methionine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with RECQL4-related disease. ClinVar contains an entry for this variant (Variation ID: 239699). The methionine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. In addition, 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, but these predictions have not been confirmed by published functional studies. 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.
