Genes affected

NCAPG2 (HGNC:21904): (non-SMC condensin II complex subunit G2) This gene encodes a protein that belongs to the Condensin2nSMC family of proteins. The encoded protein is a regulatory subunit of the condensin II complex which, along with the condensin I complex, plays a role in chromosome assembly and segregation during mitosis. A similar protein in mouse is required for early development of the embryo. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]

The c.2920G>A (p.E974K) alteration is located in exon 23 (coding exon 22) of the NCAPG2 gene. This alteration results from a G to A substitution at nucleotide position 2920, causing the glutamic acid (E) at amino acid position 974 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
