Variant summary
Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2PP3_Moderate
The NM_004260.4(RECQL4):c.1807T>C(p.Cys603Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. C603C) has been classified as Likely benign.

Baller-Gerold syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | May 18, 2016 | This sequence change replaces cysteine with arginine at codon 603 of the RECQL4 protein (p.Cys603Arg). The cysteine residue is weakly conserved and there is a large physicochemical difference between cysteine and arginine. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a RECQL4-related disease. 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 disruptive, but these predictions have not been confirmed by published functional studies. In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. - |
