Invitae | RCV001234685 | SCV001407342 | pathogenic | Nemaline myopathy 2 | 2019-11-06 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Glu4145*) in the NEB gene. This variant occurs in a region of NEB (Exons 82-105) consisting of three highly homologous 8-exon repeat units (exons 82-89, exons 90-97, exons 98-105). Sequence variants in this region can be detected, but this assay cannot determine which of the three repeat units is affected, and zygosity is often ambiguous. All variants in this region are reported relative to the exon 82-89 repeat. The frequency data for this variant in the population databases (ExAC) is considered unreliable due to the presence of homologous sequence, such as pseudogenes or paralogs, in the genome. This variant has not been reported in the literature in individuals with NEB-related conditions. Loss-of-function variants in NEB are known to be pathogenic (PMID: 25205138). For these reasons, this variant has been classified as Pathogenic. |
