LINC01644

Summary

LINC01644 (long intergenic non-protein coding RNA 1644, HGNC:52431) is a long non-coding RNA gene on chromosome 22q13.31.

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).
