| Invitae | RCV000551752 | SCV000651311 | uncertain significance | Hereditary sensory neuropathy-deafness-dementia syndrome | 2023-11-27 | criteria provided, single submitter | clinical testing | This sequence change falls in intron 36 of the DNMT1 gene. It does not directly change the encoded amino acid sequence of the DNMT1 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs199506146, gnomAD 0.07%), and has an allele count higher than expected for a pathogenic variant. This variant has not been reported in the literature in individuals affected with DNMT1-related conditions. ClinVar contains an entry for this variant (Variation ID: 472275). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. 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. |
| Ambry Genetics | RCV003159901 | SCV003887235 | likely benign | Inborn genetic diseases | 2023-03-13 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. |
