Type (0) spinal muscular atrophy associated with fractures at birth

Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disease characterized by degeneration of alpha motor neurons in the spinal cord, resulting in progressive proximal muscle weakness and paralysis. In addition to the three classical SMA types mentioned worldwide, a new form known as Type 0 with intrauterine onset in the form of fetal akinesia and profound hypotonia manifesting as birth asphyxia and a progressive, and early fatal course has been described. Here, we report a case of Type 0 SMA presenting with bilateral symmetrical fracture of long bones at birth, which has been reported miniscule in the world literature.
