Congenital myopathies: A clinicopathological study of 10 cases in a tertiary care hospital of North India.

Objective: Congenital myopathies (CMs) are rare neuromuscular disorders. Through this article, authors want to present a clinicopathological study of 10 cases of CM. Materials and Methods: The study included patients with histopathologically confirmed CM attending the neurology services at the Institute of Human Behavior and Allied Sciences for 2 years. After collecting the demographic data, all patients were subjected to comprehensive workup including a detailed neurological examination and investigations, including muscle biopsy from representative involved muscle. Results: Ten patients diagnosed with CM. The most common CM type was congenital fiber-type disproportion (CFTD) seen in four cases followed by centronuclear myopathy in two cases and one each in desmin-related myopathy, central core disease, nemaline myopathy, CM with type II fiber hypoplasia. Clinically, they have variable features. Conclusion: This study from India highlights the importance of specific clinical features to look for when suspecting a CM coupled with specific features in histopathology. However, studies with longer duration are needed to find out the true prevalence and various spectra of CMs. [ABSTRACT FROM AUTHOR]
