Genes affected

PRP4K (HGNC:17346): (pre-mRNA processing factor kinase PRP4K) Pre-mRNA splicing occurs in two sequential transesterification steps, and the protein encoded by this gene is thought to be involved in pre-mRNA splicing and in signal transduction. This protein belongs to a kinase family that includes serine/arginine-rich protein-specific kinases and cyclin-dependent kinases (CDKs). This protein is regarded as a CDK-like kinase (Clk) with homology to mitogen-activated protein kinases (MAPKs). [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.2790G>A (p.M930I) alteration is located in exon 14 (coding exon 14) of the PRPF4B gene. This alteration results from a G to A substitution at nucleotide position 2790, causing the methionine (M) at amino acid position 930 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
