Genotype
MGI:3778902
Allelic
Composition
Pnpg/Pnpg
Genetic
Background
involves: C57BL/6 * DBA/2J
Find Mice Using the International Mouse Strain Resource (IMSR)
Mouse lines carrying:
Pnpg mutation (0 available); any Pnp mutation (15 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• Background Sensitivity: reduced survival to birth but some do survive when DBA/2J is part of the background

homeostasis/metabolism
• reduced purine nucleoside phosphorylase activity in erythrocytes relative to controls

immune system
• marked and progressive decline in cellularity observable by 2-3 months of age
• 57% reduction
• thymus levels only 14% of control mice
• numbers in spleen only 41% of control numbers
• spleen leukocyte response to conA and IL-2 is impaired, being only 18-20% of normal; when adjusted for the reduction in Thy-1+ cells, overall response to conA and IL-2 is 34-38% compared to controls

hematopoietic system
• marked and progressive decline in cellularity observable by 2-3 months of age
• 57% reduction
• thymus levels only 14% of control mice
• numbers in spleen only 41% of control numbers
• spleen leukocyte response to conA and IL-2 is impaired, being only 18-20% of normal; when adjusted for the reduction in Thy-1+ cells, overall response to conA and IL-2 is 34-38% compared to controls

endocrine/exocrine glands
• marked and progressive decline in cellularity observable by 2-3 months of age
