Polyneuropathy-hand defect syndrome
MONDO:0008809Digital extensor muscle aplasia-polyneuropathy is a rare, hereditary motor and sensory neuropathy characterized by flexion deformities of the thumb and fingers, sensory deficit in the hand and polyneuropathic electrophysiologic findings in the limbs. Operation on the hands reveals extensor muscles and their tendons to be absent or hypoplastic. There have been no further descriptions in the literature since 1986.
Also known as: Hamanishi Ueba Tsuji syndrome, Hamanishi-Ueba-Tsuji syndrome, aplasia of extensor muscles of fingers, unilateral, with generalised polyneuropathy, aplasia of extensor muscles of fingers, unilateral, with generalized polyneuropathy, congenital aplasia of the extensor muscles of the fingers and thumb associated with generalised polyneuropathy, congenital aplasia of the extensor muscles of the fingers and thumb associated with generalized polyneuropathy, digital extensor muscle aplasia-polyneuropathy, polyneuropathy, hand defect

Liquid nerve biopsy could unlock ALS secrets
Knowledge-focused Recruiting nowThis study is collecting nerve samples and biofluids from 400 people with ALS or peripheral neuropathies to find biological markers for early diagnosis and disease tracking. By analyzing individual cells, researchers hope to identify molecular changes that happen before symptoms …
