Genes affected

PRPF40B (HGNC:25031): (pre-mRNA processing factor 40 homolog B) This gene encodes a WW-domain containing protein similar to yeast splicing factor PRP40. This protein has been shown to interact with Huntingtin and methyl CpG binding protein 2 (MeCP2). Alternative splicing results in different transcript variants. [provided by RefSeq, Aug 2014]

PRPF40B links:

FMNL3 (HGNC:23698): (formin like 3) The protein encoded by this gene contains a formin homology 2 domain and has high sequence identity to the mouse Wbp3 protein. Two alternative transcripts encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

The c.1883G>A (p.R628H) alteration is located in exon 19 (coding exon 19) of the PRPF40B gene. This alteration results from a G to A substitution at nucleotide position 1883, causing the arginine (R) at amino acid position 628 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
