Genes affected

CDC40 (HGNC:17350): (cell division cycle 40) Pre-mRNA splicing occurs in two sequential transesterification steps. The protein encoded by this gene is found to be essential for the catalytic step II in pre-mRNA splicing process. It is found in the spliceosome, and contains seven WD repeats, which function in protein-protein interactions. This protein has a sequence similarity to yeast Prp17 protein, which functions in two different cellular processes: pre-mRNA splicing and cell cycle progression. It suggests that this protein may play a role in cell cycle progression. [provided by RefSeq, Jul 2008]

The c.1646A>C (p.H549P) alteration is located in exon 15 (coding exon 15) of the CDC40 gene. This alteration results from a A to C substitution at nucleotide position 1646, causing the histidine (H) at amino acid position 549 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
