Invitae | RCV000542569 | SCV000640739 | pathogenic | Nemaline myopathy 2 | 2019-12-31 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Leu8106Phefs*30) in the NEB gene. It is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). 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. |
Integrated Genetics/Laboratory Corporation of America | RCV000588489 | SCV000697817 | likely pathogenic | Nemaline myopathy | 2017-03-20 | criteria provided, single submitter | clinical testing | Variant summary: The NEB c.24314_24317dupTGTT (p.Leu8106Phefs) variant results in a premature termination codon, predicted to cause a truncated or absent NEB protein due to nonsense mediated decay, which are known disease mechanisms in nemaline myopathy. This variant is absent in 34482 control chromosomes from ExAC. This variant is reported in one family with typical nemaline myopathy in compound heterozygous state with c.1172_1173del (p.Tyr391*) (Lehtokari_2014). No genotypic and phenotypic details of the family members are provided in the study. It was also found in three colorectal cancer samples without confirmation of somatic status in COSMIC database. Truncations downstream of this position have been classified as pathogenic by our laboratory and other labs in ClinVar (e.g. p.Arg8187X, c.24771delT, c.24632_24633delCT). Taken together, this variant is classified as likely pathogenic. |
