Distal hereditary motor neuropathy type 3 and type 4 (Q103447): Difference between revisions

Several kinds have been reported with slowly progressive distal spinal muscular atrophy and autosomal recessive inheritance. Onset of symptoms may develop in infancy or early childhood, or may be delayed into early adulthood. Although relatively benign, ambulation is typically affected. Initially thought to be separate entities due to the variability in age of onset, Distal hereditary motor neuropathy type 3 and 4 have been identified in the same family suggesting a common gene. The responsible gene has been mapped to chromosome 11q13.3.
