Summaries for Spinal Muscular Atrophy, Distal, X-Linked 3

UniProtKB/Swiss-Prot : 75 Distal spinal muscular atrophy, X-linked, 3: A neuromuscular disorder. Distal spinal muscular atrophy, also known as distal hereditary motor neuronopathy, represents a heterogeneous group of neuromuscular disorders caused by selective degeneration of motor neurons in the anterior horn of the spinal cord, without sensory deficit in the posterior horn. The overall clinical picture consists of a classical distal muscular atrophy syndrome in the legs without clinical sensory loss. The disease starts with weakness and wasting of distal muscles of the anterior tibial and peroneal compartments of the legs. Later on, weakness and atrophy may expand to the proximal muscles of the lower limbs and/or to the distal upper limbs.

MalaCards based summary : Spinal Muscular Atrophy, Distal, X-Linked 3, also known as smax3, is related to neuropathy and charcot-marie-tooth hereditary neuropathy. An important gene associated with Spinal Muscular Atrophy, Distal, X-Linked 3 is ATP7A (ATPase Copper Transporting Alpha). Affiliated tissues include spinal cord, and related phenotypes are pes cavus and hyporeflexia
