Genes affected

ROCK2 (HGNC:10252): (Rho associated coiled-coil containing protein kinase 2) The protein encoded by this gene is a serine/threonine kinase that regulates cytokinesis, smooth muscle contraction, the formation of actin stress fibers and focal adhesions, and the activation of the c-fos serum response element. This protein, which is an isozyme of ROCK1 is a target for the small GTPase Rho. [provided by RefSeq, Jul 2008]

ROCK2 Gene-Disease associations (from GenCC):

• congenital heart disease

  Inheritance: AD Classification: MODERATE, LIMITED Submitted by: ClinGen, PanelApp Australia

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
