CTXN2-AS1

Summary

CTXN2-AS1 (CTXN2 antisense RNA 1, HGNC:55426) is a long non-coding RNA gene on chromosome 15q21.1.

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).
