Genes affected

CDC5L (HGNC:1743): (cell division cycle 5 like) The protein encoded by this gene shares a significant similarity with Schizosaccharomyces pombe cdc5 gene product, which is a cell cycle regulator important for G2/M transition. This protein has been demonstrated to act as a positive regulator of cell cycle G2/M progression. It was also found to be an essential component of a non-snRNA spliceosome, which contains at least five additional protein factors and is required for the second catalytic step of pre-mRNA splicing.

The CDC5L c.147A>G variant is not predicted to result in an amino acid change (p.=). However, this variant is predicted to possibly weaken the canonical donor splice site (Alamut Visual Plus v1.6.1). To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0018% of alleles in individuals of European (non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
