Invitae RCV001066632 SCV001231647 uncertain significance Hereditary sensory neuropathy-deafness-dementia syndrome 2022-07-26 criteria provided, single submitter clinical testing ClinVar contains an entry for this variant (Variation ID: 860348). 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 sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. This variant has not been reported in the literature in individuals affected with DNMT1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change affects a donor splice site in intron 11 of the DNMT1 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), however the current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in DNMT1 cause disease.
