Affected Children of Healthy Parents: Multiple Pediatric Cases of Autosomal Recessive Charcot-Marie-Tooth Disease in a Pakistani Family

: Charcot-Marie-Tooth (CMT) disease, also referred to as hereditary motor and sensory neuropathy (HMSN), is a heterogeneous group of disorders which primarily affects the peripheral nervous system. Clinically, the main features are progressive muscle weakness seen distally, along with wasting seen predominantly in the anterior compartments of the lower legs. The disease can broadly be classified into two groups, CMT1 and CMT2-based on inheritance patterns, paired with anatomical or electrophysiological findings. It can be inherited in the autosomal dominant, X-linked and rarely, the autosomal recessive fashions. Here, we present an unusual case of autosomal recessive CMT disease, in four out of six children of unaffected parents in a family.
