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]

Nov 21, 2023

The c.1396G>A (p.A466T) alteration is located in exon 13 (coding exon 13) of the CDC40 gene. This alteration results from a G to A substitution at nucleotide position 1396, causing the alanine (A) at amino acid position 466 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
