Gene Expression + Phenotype

Most homozygous mutants die within 48 hours after birth. Surviving mutants have reduced body size, skin lesions, enlarged intestines, and die by 6 months of age from ruptured blood vessels. Occasionally intestinal rupture also results in early death. Heterozygotes exhibit tight skin.
