ABSTRACT
Hereditary motor and sensory neuropathy with proximal predominance (HMSN-P) is a rare degenerative disorder inherited in an autosomal dominant fashion. This disease was described first in Japanese descendants from Okinawa and Shiga prefectures in mainland Honshu in 1997. The disease is characterized by adult onset of proximal weakness and atrophy, muscle cramps, fasciculations, areflexia, high incidence of elevated creatine kinase, hyperlipidemia, and diabetes mellitus, resembling Kennedy disease, though the mode of inheritance is autosomal dominant, rather than X linked. We examined a 56-year-old male patient with clinical features suggestive of HMSN-P and positive family history in an autosomal dominant fashion. Clinical, electrophysiological, and genetic factors were also reviewed. The appearance of HMSN-P in India and elsewhere calls for clinicians in nonendemic regions to be familiar with this rare disorder, which has typically been geographically confined.
