TTTY23

Summary

TTTY23 (testis expressed transcript, Y-linked 23, HGNC:18847) is a long non-coding RNA gene on chromosome Yp11.2.

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).
