SMN2 که برگرفته از عبارت «بقای سلول عصبی حرکتی ۲» (انگلیسی: Survival of motor neuron 2‎) است، نام یک ژن است که در انسان، پروتئین SMN را کد می‌کند.[4][5]

با آنکه جهش در نسخهٔ تلومری ژن (یعنی SMN1) با بروز بیماری آتروفی عضلانی نخاعی در ارتباط است؛ اما جهش در SMN2 (نسخهٔ سانترومری آن) موجب بروز این بیماری نمی‌شود.
