New Approaches and Approved Drugs in Spinal Muscular Atrophy (SMA) Treatment

Abstract: Spinal musküler atrofi (SMA), survival motor neuron (SMN1) genindeki delesyonlar veya mutasyonların neden olduğu otozomal resesif bir nöromusküler bir hastalıktır. Çocuk ölümlerinin en yaygın kalıtsal nedenidir. SMN1, tüm ökaryotik organizmaların genomunda tek kopya olarak bulunur. Genomik duplikasyon ile ikinci bir gen SMN2 insanlarda ortaya çıkmıştır. Hastaların yaklaşık %95'i SMN1 geninin ekzon 7'sinde homozigot delesyonlara sahiptir. Bundan dolayı SMN proteini yeterli miktarda üretilemez. SMN2, ekzon 7'dek… Show more

“…SMA is caused by homozygous omission or loss-of-function mutations in the gene SMN1 (Survival Motor Neuron 1) [1]. Age of onset, 0-6 months Type I (Werdnig-Hoffmann) SMA is the strongest and most severe stage, generally leading to death before 2 times [1]. Type II SMA patients are moderately affected, with age before 18 months [1].…”
