LINC02303

Summary

LINC02303 (long intergenic non-protein coding RNA 2303, HGNC:53222) is a long non-coding RNA gene on chromosome 14q21.2.

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).
