spinal mus·cu·lar at·ro·phy type III

[MIM*253400]
the juvenile form, with onset in childhood or adolescence; characterized by progressive proximal muscular weakness and wasting, primarily in the pelvic girdle, followed by distal muscle involvement; caused by degeneration of motor neurons in the anterior horns of the spinal cord; autosomal recessive inheritance, caused by mutation in the SMN1 gene on 5q.

SMA type III, also called Kugelberg-Welander disease, appears between 2 and 17 years of age and includes abnormal gait; difficulty running, climbing steps, or rising from a chair; and slight tremor of the fingers (NINDS, 2007).
Type III SMA (Kugelberg-Welander disease; MIM# 253400) is a mild form of the disease with onset after the age of 18 months (4), and with patients gaining the ability to walk.
Infantile spinal muscular dystrophy includes 3 subtypes: type 1 (acute, fatal) or Werdnig-Hoffman disease; type 2, intermediate; and type 3, chronic or Kugelberg-Welander disease. Werdnig-Hoffman disease is a neuromuscular disorder caused by loss of anterior horn cells and motor nuclei of cranial nerves V through VIII.

Werdnig-Hoffmann disease is sometimes used for type 1 SMA and Kugelberg-Welander disease for type 3.
ALS is also called a "motor neuron disease;" which is a general term that refers to a group of disorders that also includes Werdnig-Hoffmann disease, intermediate spinal muscular atrophy, Kugelberg-Welander disease and Aran-Duchenne spinal muscular atrophy.
