LSAMP-AS1

Summary

LSAMP-AS1 (LSAMP antisense RNA 1, HGNC:40350) is a long non-coding RNA gene on chromosome 3q13.31.

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).
