| A rare autosomal recessive distal hereditary motor neuropathy with characteristics of slowly progressive muscular weakness, hypotonia and atrophy of the lower limbs, more pronounced distally, leading to paralysis, and loss of tendon reflexes. Additional features may include pes cavus and mild dysphonia. The upper limbs are relatively spared. There is evidence this disease is caused by homozygous mutation in the DNAJB2 gene on chromosome 2q35. |
