Mouse lines carrying:
Dnase1tm1Tmo mutation (0 available); any Dnase1 mutation (28 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• some homozygotes display symptoms of systemic lupus erythematosus at 6-8 months of age and die

immune system
• 17/49 homozygotes exhibit splenomegaly
• Background Sensitivity: on a mixed 129/B6 background, mice develop symptoms similar to systemic lupus erythematosus
• mice show anti-nuclear antibodies
• 56% of male mice and 73% of female mice display anti-nuclear antibodies compared to 15% of male and 35% of female wild-type mice
• 21/49 show perivascular leukocytic infiltration in the kidney
• in males, 19% show glomerulonephritis compared to 0% of wild-type; 31% of female heterozygotes show glomerulonephritis compared to 12% in wild-type
• numbers in females are likely higher because numerous deficiet female animals could not be analyzed due to high autolysis

hematopoietic system
• 17/49 homozygotes exhibit splenomegaly

renal/urinary system
• 21/49 show perivascular leukocytic infiltration in the kidney
• in males, 19% show glomerulonephritis compared to 0% of wild-type; 31% of female heterozygotes show glomerulonephritis compared to 12% in wild-type
• numbers in females are likely higher because numerous deficiet female animals could not be analyzed due to high autolysis

growth/size/body
• 17/49 homozygotes exhibit splenomegaly
