Distal spinal muscular atrophy with vocal cord paralysis.

Hereditary distal muscular atrophy with vocal cord paralysis and sensorineural hearing loss: a dominant form of spinal muscular atrophy?

In 1980 Young and Harper described a family with an unusual form of distal spinal muscular atrophy associated with vocal cord paralysis. We report a family with three similarly affected subjects. Progressive sensorineural hearing loss was an additional feature in our patients. Electrophysiological and histological investigations did not exclude an involvement of sensory neurones. Whether the cl...

Hereditary distal spinal muscular atrophy with vocal cord paralysis.

A large kindred is described in which an unusual form of spinal muscular atrophy is segregating in an autosomal dominant manner. The disease presents most commonly in the teens with small muscle wasting in the hands, particularly involving median nerve musculature. Subsequently distal muscle wasting and weakness occur in the lower limbs. Vocal cord paralysis is a characteristic and potentially ...

Distal spinal muscular atrophy with vocal cord paralysis (dSMA-VII) is not linked to the MPD2 locus on chromosome 5q31.

Distal spinal muscular atrophy with vocal cord paralysis (dSMA-VII) is not linked to the MPD2 locus on chromosome 5q31 EDITOR—Hereditary distal limb weakness and atrophy is a heterogeneous condition that may be neurogenic or myopathic in origin. Hereditary motor and sensory neuropathy (HMSN) I and II (also known as Charcot-Marie-Tooth (CMT) 1 and 2), distal spinal muscular atrophy (dSMA), and t...

Clinical and genetic heterogeneity in peroneal muscular atrophy associated with vocal cord weakness.

BACKGROUND The peroneal muscular atrophy syndrome is the most common inherited disorder of the peripheral nervous system and has extensive clinical and genetic heterogeneity. Cranial nerve involvement is rare, though there are distinct peroneal muscular atrophy syndromes in which vocal cord paralysis is a characteristic feature. Among these dHMN-VII and HMSN-IIC are clinically similar but are d...
