GeneDx RCV000490070 SCV000577325 likely pathogenic not provided 2019-06-25 criteria provided, single submitter clinical testing Not observed in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; Has not been previously published as pathogenic or benign to our knowledge
Invitae RCV002527032 SCV003259855 uncertain significance Hereditary sensory neuropathy-deafness-dementia syndrome 2021-12-21 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals affected with DNMT1-related conditions. 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: "Possibly Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 426790). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 1256 of the DNMT1 protein (p.Tyr1256Cys).
