mortality/aging

premature death ( J:115193 )

• mice die suddenly within a few days after weaning (average lifespan ~23.8 days); even if mutants are left with the mother, survival is <30 days

growth/size/body

decreased body weight ( J:115193 )

• at P8, triple mutants weigh less than their littermates and at P20 are ~50% of wild-type littermates

nervous system

neurodegeneration ( J:115193 )

• degenerating neurons are found in brain and spinal cord of mutants

• mice show accelerated degeneration relative to Dnajc5-null animals at 10 days of age

N	normal phenotype

nervous system

abnormal striatum morphology ( J:93544 )

• dopamine levels decreased by 18% in the striatum but metabolic levels are normal

homeostasis/metabolism

decreased dopamine level ( J:93544 )

• dopamine levels decreased by 18% in the striatum but metabolic levels are normal
