Muscular dystrophy and myopathy_Paediatric v0.128 TPM3 Sangavi Sivagnanasundram edited their review of gene: TPM3: Changed mode of pathogenicity: Other
Muscular dystrophy and myopathy_Paediatric v0.128 TPM3 Sangavi Sivagnanasundram gene: TPM3 was added
gene: TPM3 was added to Muscular dystrophy_Paediatric. Sources: Other
Mode of inheritance for gene: TPM3 was set to BOTH monoallelic and biallelic, autosomal or pseudoautosomal
Publications for gene: TPM3 were set to 26418456; 18300303; 10619715; 12196661; 18382475
Phenotypes for gene: TPM3 were set to Congenital myopathy 4A, autosomal dominant (MIM#255310); Congenital myopathy 4B, autosomal recessive (MIM#609284)
Review for gene: TPM3 was set to GREEN
Added comment: Variable age of onset due to the variability of phenotypes. Mutations in TPM3 cause a diverse group of congenital myopathies all characterised by muscle weakness/hypotonia.

AD Congenital Myopathy:
PMID: 26418456
Quantitative in vitro motility assay show that gain of function is mechanism of disease - mutations in the TPM3 gene led to an increased function in the myofibres/muscle cells.
2 unrelated individuals with ΔE218 and ΔE224 de novo deletions in TPM3 with muscle stiffness. Both muscle biopsies showed features of mild myopathy.
