Hydrocephalus
Gene: MTM1
As discussed with the GMS Neurology Specialist Test Group webex call 11th July 2019: The Specialist Test Group all agreed that there is only enough evidence to rate this gene AmberCreated: 29 Jul 2019, 2:49 p.m. | Last Modified: 29 Jul 2019, 2:49 p.m.

Clear causation for MTM1 and the phenotype, however hydrocephalus is not a consistent feature. PMID 8588581 reports the presence in several patients based upon clinical ascertainment, however PMID 9931531 contains a review of many more cases and it is only noted in one. On balance, unlikely to be beneficial for this panel as it is not a clear feature and profound weakness would prompt presentation via other routes.Created: 9 May 2017, 1:22 p.m.

Mode of inheritance for gene: MTM1 was changed from X-LINKED: hemizygous mutation in males, biallelic mutations in females to X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)
Phenotypes for gene: MTM1 were changed from Myotubular myopathy, X-linked, OMIM:310400 to Myopathy, centronuclear, X-linked, OMIM:310400
Phenotypes for gene: MTM1 were changed from Myotubular myopathy, X-linked to Myotubular myopathy, X-linked, OMIM:310400
