C4B-AS1

Summary

C4B-AS1 (C4B antisense RNA 1, HGNC:39752) is a long non-coding RNA gene on chromosome 6p21.33.

At a glance

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