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 c.586A>T (p.I196L) alteration is located in exon 6 (coding exon 6) of the CDC5L gene. This alteration results from a A to T substitution at nucleotide position 586, causing the isoleucine (I) at amino acid position 196 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
