MGI:1101779Mice homozygous for a targeted allele exhibit increased sensitivity to cardiac pressure overload, including increased hypertrophy, decreased ejection fraction, decreased microvessel number, increased extracellular matrix deposition and increased fibrosis. Homozygous KO leads to impaired wound healing and delayed retinal vasculature development and affects macrophage differentiation. Homozygosity for the p.A389P mutation leads to enhanced wound healing and accelerated retinal vasculature development and affects macrophage differentiation.
