Abstract
Proximal spinal muscular atrophy (SMA) is an autosomal recessive disease in humans and other mammals, characterized by degeneration of anterior horn cells of the spinal cord. In humans, the survival of motor neuron gene (SMN) has been recognized as the SMA-determining gene and has been mapped to 5q13. In cattle, SMA is a recurrent, inherited disease that plays an important economic role in breeding programs of Brown Swiss stock. Now we have identified the full- length cDNA sequence of the bovine SMN gene. Molecular analysis and characterization of the sequence documents 85% identity to its human counterpart and three evolutionarily conserved domains in different species. Physical mapping data reveals that bovine SMN is localized to chromosome region 20q12→q13, supporting the conserved synteny of this chromosomal region between humans and cattle.Keywords
