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]
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 08, 2024The c.1750C>T (p.H584Y) alteration is located in exon 18 (coding exon 18) of the PRPF40B gene. This alteration results from a C to T substitution at nucleotide position 1750, causing the histidine (H) at amino acid position 584 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
