| | Survival Motor Neuron Gene Deletion in the Arthrogryposis Multiplex Congenita-Spinal Muscular Atrophy Association -- ... |
 | | Recently, we have identified the survival motor neuron (SMN) gene as the SMA-determining gene, since it is either absent or interrupted in 90-100% of typical SMA patients (5, 6, 7) and patients retaining the gene carried intragenic SMN mutations (5, 7). |
 | | Indeed, atypical forms of infantile SMA with cerebellar hypoplasia, pontocerebellar degeneration, multiple long bone fractures at birth or congenital heart defects (CHD) have been described and could represent separate entities with a different genetic basis (4, 9). |
