Genes affected

ANAPC2 (HGNC:19989): (anaphase promoting complex subunit 2) A large protein complex, termed the anaphase-promoting complex (APC), or the cyclosome, promotes metaphase-anaphase transition by ubiquitinating its specific substrates such as mitotic cyclins and anaphase inhibitor, which are subsequently degraded by the 26S proteasome. Biochemical studies have shown that the vertebrate APC contains eight subunits. The composition of the APC is highly conserved in organisms from yeast to humans. The product of this gene is a component of the complex and shares sequence similarity with a recently identified family of proteins called cullins, which may also be involved in ubiquitin-mediated degradation.

The c.1277G>A (p.R426H) alteration is located in exon 6 (coding exon 6) of the ANAPC2 gene. This alteration results from a G to A substitution at nucleotide position 1277, causing the arginine (R) at amino acid position 426 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
