Genes affected

SRRM2 (HGNC:16639): (serine/arginine repetitive matrix 2) Enables C2H2 zinc finger domain binding activity and protein N-terminus binding activity. Involved in mRNA splicing, via spliceosome. Located in Cajal body and nuclear speck. Part of U2-type catalytic step 2 spliceosome and U2-type precatalytic spliceosome. Biomarker of Parkinson's disease.
