Congenital fibre type disproportion associated with mutations in the tropomyosin 3 (TPM3) gene mimicking congenital myasthenia.
Congenital myopathy with fibre type disproportion (CFTD) has been associated with mutations in ACTA1, SEPN1, RYR1 and TPM3 genes. We report the clinico-pathological and electrophysiological features of 2 unrelated cases with heterozygous TPM3 mutation. Case 1 is a 19-year-old lady who presented with motor delay in infancy, respiratory failure in early teens requiring non-invasive ventilation despite being ambulant, ptosis, axial more than proximal weakness and scoliosis. Case 2 is a 7-year-ol...Expand abstract
