SNORA21B

Summary

SNORA21B (small nucleolar RNA, H/ACA box 21B, HGNC:52195) is a small nucleolar RNA gene on chromosome 17q12.

At a glance

• Gene type: non-coding (snoRNA) — no protein product; not a drug target. Variant/disease associations are omitted (they would be positional, from an overlapping protein-coding gene).
