Invitae | RCV002532086 | SCV003028042 | uncertain significance | Mucopolysaccharidosis, MPS-III-B; Charcot-Marie-Tooth disease axonal type 2V | 2020-06-01 | criteria provided, single submitter | clinical testing | This sequence change results in a premature translational stop signal in the NAGLU gene (p.Arg720*). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 24 amino acids of the NAGLU protein. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with NAGLU-related conditions. ClinVar contains an entry for this variant (Variation ID: 553778). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. 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. |
