Abstract

The gene for autosomal recessive neurodegenerative disorder Spinal Muscular Atrophy has been mapped to a region of chromosome 5. The gene encodes a protein having homology with apoptosis inhibitor proteins of viruses so that the encoded protein has been labelled as a neuronal apoptosis inhibitor protein (NAIP). A deletion in the (NAIP) domain was identified in persons with Type I, II and III Spinal Muscular Atrophy (SMA) and not in the normal non-SMA population.
