Autosomal Dominant Childhood-onset Proximal Spinal Muscular Atrophy Without Contractures

Description

Spinal muscular atrophy (SMA) is a hereditary neuromuscular disorder characterized by degeneration of spinal cord motor neurons resulting in muscle weakness. SMALED shows autosomal dominant inheritance with muscle weakness predominantly affecting the proximal lower extremities (Harms et al., 2010).The most common form of SMA (see, e.g., SMA1, {253300}) shows autosomal recessive inheritance and is due to mutation in the SMN1 gene (OMIM ) on chromosome 5q. Genetic Heterogeneity of Lower Extremity-Predominant Spinal Muscular AtrophySee also SMALED2 (OMIM ), caused by mutation in the BICD2 gene (OMIM ) on chromosome 9q22.
