Genes affected
PRPF31 (HGNC:15446): (pre-mRNA processing factor 31) This gene encodes a component of the spliceosome complex and is one of several retinitis pigmentosa-causing genes. When the gene product is added to the spliceosome complex, activation occurs.[provided by RefSeq, Jan 2009]
PRPF31-AS1 (HGNC:40700): (PRPF31 antisense RNA 1)
