1208413008: Congenital fiber-type disproportion myopathy due to actin alpha 1, skeletal muscle mutation (disorder)

• SNOMED CT Concept\Clinical finding (finding)\...
• \General finding of soft tissue\Disorder of soft tissue\Disorder of skeletal muscle\Congenital anomaly of skeletal muscle\Myopathy with abnormality of histochemical fibre type\A rare genetic congenital non-dystrophic myopathy characterised by neonatal or infantile-onset hypotonia and mild to severe generalised muscle weakness. Limb weakness may be greatest in the limb girdle and proximal limb muscles, but weakness is never solely distal. Facial weakness is often present, resulting in a long face, high-arched palate, and tented upper lip. Histologically, there is a characteristic (but not specific) reduction in the caliber of type 1 muscle fibres. Type 1 muscle fibres are predominant compared to type 2 fibres, which are either normal or hypertrophied. Causative mutations have been identified more frequently in 4 genes, ACTA1 (1q42.13), RYR1 (19q13.2), TPM3 (1q21.3), and SELENON (1p36.11). For the majority of cases the pattern of inheritance is either autosomal recessive or autosomal dominant. X-linked inheritance has been reported.\A rare genetic congenital non-dystrophic myopathy characterised by neonatal or infantile-onset hypotonia and mild to severe generalised muscle weakness. Causative gene mutation is ACTA1 (1q42.13).
