Homozygous null mice show genomic instability, thymus hyperplasia, elevated radiation carcinogenesis, abnormal parturition and low frequency exencephaly. Females develop a lupus-like syndrome associated with high titers of autoantibodies, hematologic deficits, glomerulonephritis and premature death.
