N normal phenotype
mortality/aging
• 50% of triple Rab3 knockouts with one copy of Rab3c survive

growth/size/body
• male and female triple knockouts which are deficient for Rab3a and heterozygous for Rab3b display a weight decrease at 5 weeks of age

respiratory system
• triple knockouts lacking Rab3a show respiratory impairment similar to, but less severe than that shown by quadruple knockouts
