Homozygous null mice exhibit prenatal, perinatal and neonatal lethality, impaired lung maturation, respiratory failure, craniofacial defects, and reduced fibroblast proliferation. Heterozygotes show premature death, early-onset aging phenotypes including lordokyphosis, muscle atrophy, loss of subcutaneous fat and increased tumor incidence, and mitochondrial defects.
