Genes affected

ZRSR2 (HGNC:23019): (zinc finger CCCH-type, RNA binding motif and serine/arginine rich 2) This gene encodes an essential splicing factor. The encoded protein associates with the U2 auxiliary factor heterodimer, which is required for the recognition of a functional 3' splice site in pre-mRNA splicing, and may play a role in network interactions during spliceosome assembly.
