Genes affected
PRPF4B (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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 26, 2022The c.571C>T (p.R191W) alteration is located in exon 2 (coding exon 2) of the PRPF4B gene. This alteration results from a C to T substitution at nucleotide position 571, causing the arginine (R) at amino acid position 191 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
