پلی‌پپتید اِن وابسته به ریبونوکلئوپروتئین هسته‌ای کوچک (انگلیسی: Small nuclear ribonucleoprotein-associated polypeptide N) یک پروتئین است که در انسان توسط ژن «SNRPN» کُدگذاری می‌شود.^[۳]^[۴] این پروتئین متعلق به خانوادهٔ اس‌ان‌آران‌پی «SMB/SMN» است که در پردازش‌های پیش از mRNA و به‌ویژه پیرایش دگرسان اختصاصی بافت‌ها نقش دارد.

اهمیت بالینی

پیرایش دگرسان یا حذف ژنی در اثر جابه‌جایی کروموزومی در این ناحیه ژنی که از پدر به ارث می‌رسد، می‌تواند باعث بروز سندرم پرادر–ویلی گردد.^[۴] از متیلاسیون این ژن در تشخیص دیزومی تک‌والدی در کروموزوم ۱۵ استفاده می‌شود.^[۵]
