Spinal M\u00fcsk\u00fcler Atrofi (SMA) Nedir? <\/strong><\/p>\n

Spinal M\u00fcsk\u00fcler Atrofi (SMA), SMN1 (Survival Motor Neuron 1) genindeki bir mutasyon nedeniyle ortaya \u00e7\u0131kan genetik bir bozukluktur. SMN1 geni, motor n\u00f6ronlar\u0131n sa\u011fl\u0131kl\u0131 bir \u015fekilde \u00e7al\u0131\u015fmas\u0131 i\u00e7in gerekli olan bir protein olan SMN (Survival Motor Neuron) proteininin yap\u0131m\u0131ndan sorumludur.<\/p>\n

Normalde, SMN proteininin \u00fcretimi, bir yedekleyici gen olan SMN2 taraf\u0131ndan da sa\u011flan\u0131r. Ancak SMN2 geni, SMN1 geninden farkl\u0131 olarak, fonksiyonel SMN proteininin daha az miktar\u0131n\u0131 \u00fcretir ve bu nedenle SMN1 genindeki bir mutasyon SMN proteininin d\u00fczg\u00fcn \u00fcretimini engellerse, SMA semptomlar\u0131 ortaya \u00e7\u0131kar.<\/p>\n

SMA hastalar\u0131nda hastal\u0131\u011f\u0131n \u015fiddeti farkl\u0131l\u0131k g\u00f6stermektedir. SMA’da hastal\u0131\u011f\u0131n \u015fiddeti, hastan\u0131n sahip oldu\u011fu SMN2 geni kopya say\u0131s\u0131na ba\u011fl\u0131d\u0131r. Dolay\u0131s\u0131yla SMN2 kopya say\u0131s\u0131 artt\u0131k\u00e7a hastal\u0131\u011f\u0131n \u015fiddetinin azalmas\u0131 beklenmektedir.<\/p>\n

Son y\u0131llarda, FDA onayl\u0131 iki gen terapisi, SMA tedavisinde \u00f6nemli bir ilerleme kaydetmi\u015ftir. Bu tedaviler, SMN proteininin yap\u0131m\u0131n\u0131 art\u0131rmak i\u00e7in tasarlanm\u0131\u015ft\u0131r. SMN1 genine d\u0131\u015far\u0131dan sa\u011flanan i\u015flevsel bir kopya veya SMN2 geninin SMN1 genine daha fazla i\u015flevsel kopya \u00fcretmesini sa\u011flayan tedaviler, SMA hastalar\u0131n\u0131n ya\u015fam kalitesini ve ya\u015fam s\u00fcresini art\u0131rmada umut verici sonu\u00e7lar vermektedir.<\/p>\n\n\n\n\n\n\n\n\n
