RNA, U4atac small nuclear (U12-dependent splicing) is a small nuclear RNA that in humans is encoded by the RNU4ATAC gene.

The small nuclear RNA (snRNA) encoded by this gene is part of the U12-dependent minor spliceosome complex. In addition to the encoded RNA, this ribonucleoprotein complex consists of U11, U12, U5, and U6atac snRNAs. The U12-dependent spliceosome is required for the splicing of approximately 700 specific introns in the human genome. Defects in this gene are a cause of several human inherited syndromes all of which show autosomal recessive inheritance. These include Taybi Linder syndrome, microcephalic osteodysplastic primordial dwarfism type 1 (MOPD1), Roifman Syndrome and Lowry-Wood Syndrome. The RNU4ATAC gene is located on Chromosome 2 (2q14.2). It is a single copy gene that is embedded within an intron of the protein coding CLASP1 gene but is transcribed in the antisense direction from CLASP1.
