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 links:

TFPT (HGNC:13630): (TCF3 fusion partner) Predicted to enable DNA binding activity and protein kinase binding activity. Involved in apoptotic signaling pathway. Located in nucleoplasm. Part of Ino80 complex. [provided by Alliance of Genome Resources, Apr 2022]
