Genes affected

ESPL1 (HGNC:16856): (extra spindle pole bodies like 1, separase) Stable cohesion between sister chromatids before anaphase and their timely separation during anaphase are critical for chromosome inheritance. In vertebrates, sister chromatid cohesion is released in 2 steps via distinct mechanisms. The first step involves phosphorylation of STAG1 (MIM 604358) or STAG2 (MIM 300826) in the cohesin complex. The second step involves cleavage of the cohesin subunit SCC1 (RAD21; MIM 606462) by ESPL1, or separase, which initiates the final separation of sister chromatids (Sun et al., 2009 [PubMed 19345191]).[supplied by OMIM, Nov 2010]

The c.1291A>C (p.K431Q) alteration is located in exon 5 (coding exon 4) of the ESPL1 gene. This alteration results from a A to C substitution at nucleotide position 1291, causing the lysine (K) at amino acid position 431 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
