Invitae | RCV000708212 | SCV000837322 | likely pathogenic | Severe X-linked myotubular myopathy | 2017-12-19 | criteria provided, single submitter | clinical testing | This variant is an in-frame deletion of the genomic region encompassing exon 11 of the MTM1 gene. It preserves the integrity of the reading frame. This deletion has not been reported in the literature in individuals with MTM1-related disease. At least one missense substitution encompassed by this deletion (p.Glu404Lys) has been determined to be pathogenic (PMID: 9285787, 19084976, 25957634, 17005396, 12118066). This suggests that the Glu residue is critical for MTM1 protein function, and that other variants that disrupt it may also be pathogenic. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. |
