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]

NCAPG2 Gene-Disease associations (from GenCC):

• Khan-Khan-Katsanis syndrome

  Inheritance: AR, Unknown Classification: LIMITED Submitted by: Illumina, Ambry Genetics, ClinGen, Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85).
