Congenital muscular dystrophy and congenital myopathy
Gene: MSTO1This panel is being created as a combination of the Congenital myopathy and Congenital muscular dystrophy panels. Currently on the Congenital muscular dystrophy panel this gene has a mode of inheritance of 'Both mono and biallelic' so I have reverted the mode of inheritance on this panel to reflect that, and added the Q2_24_MOI tag to this gene on this panel to propose a MOI change due to the report in the Gal et al 2023 (see review below).Created: 6 Apr 2024, 3:42 p.m. | Last Modified: 6 Apr 2024, 3:42 p.m.

Gal et al (2017) reported a family with autosomal dominant mitochondrial myopathy and ataxia caused by a monoallelic MSTO1 variant (PMID: 28554942). Subsequently, the variant involved (rs762798018) has been reclassified as a variant of unknown significance, this is because Gal et al (2023)(PMID:37431817) have retracted their claim that there is a direct link between the variant and the patients' myopathy and ataxia phenotypes.
There are no further reports of monoallelic Myopathy, mitochondrial, and ataxia (OMIM:617675).Created: 20 Feb 2024, 1:06 p.m. | Last Modified: 20 Feb 2024, 1:06 p.m.

Panel Version: 2.7
Mode of inheritance
BIALLELIC, autosomal or pseudoautosomal
Comment on list classification: Promoted from red to green. MSTO1 is associated with a phenotype in OMIM but not in Gene2Phenotype. There are >3 unrelated cases (PMID: 28544275; 28554942; 31130378;29339779) of patients with different variants in this gene who have muscular dystrophy.Created: 6 Aug 2019, 3:38 p.m. | Last Modified: 7 Aug 2019, 10:49 a.m.
Panel Version: 1.58
Comment on mode of inheritance: PMID: 28554942 reported on a case of patient who is heterozygous for a variant in this gene. While the other PMIDs reported on biallelic cases.Created: 6 Aug 2019, 3:30 p.m. | Last Modified: 6 Aug 2019, 3:30 p.m.
