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.
