TTTY9A

Summary

TTTY9A (testis expressed transcript, Y-linked 9A, HGNC:18490) is a long non-coding RNA gene on chromosome Yq11.222.

This gene is transcribed but does not appear to encode a protein. Two identical copies of this gene are present in a palindromic region (P4) on chromosome Y. This record represents the more telomeric copy.

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).
