Invitae RCV002227999 SCV000825752 pathogenic Centromeric instability of chromosomes 1,9 and 16 and immunodeficiency 2024-01-06 criteria provided, single submitter clinical testing This sequence change replaces valine, which is neutral and non-polar, with glycine, which is neutral and non-polar, at codon 726 of the DNMT3B protein (p.Val726Gly). This variant is present in population databases (rs121908941, gnomAD 0.002%). This missense change has been observed in individual(s) with DNMT3B-related conditions (PMID: 10588719, 10647011, 11102980, 17893117, 23486536). It has also been observed to segregate with disease in related individuals. This variant is also known as V718G. ClinVar contains an entry for this variant (Variation ID: 6735). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on DNMT3B protein function. Experimental studies have shown that this missense change affects DNMT3B function (PMID: 11741835, 16543361). For these reasons, this variant has been classified as Pathogenic.
