Lung development is affected in Sec24bkrb/Sec24bkrb embryos

mortality/aging

hearing/vestibular/ear
• at E16.5, the cochlea is smaller than in wild-type mice
• the organ of Corti is decreased in length compared to in wild-type mice
• at E17.5, the organ of Corti is disorganized unlike in wild-type mice
• mice exhibit out of line and misoriented inner hair cells in the organ of Corti unlike wild-type mice
• mice exhibit supernumerary rows of outer hair cells unlike wild-type mice

nervous system
• severe in 95% of mice with remaining mice exhibiting a weaker phenotype
• mice exhibit out of line and misoriented inner hair cells in the organ of Corti unlike wild-type mice
• mice exhibit supernumerary rows of outer hair cells unlike wild-type mice

cardiovascular system
• at E16.5, mice exhibit abnormal orientation of the great outflow vessels unlike wild-type mice
• at E15.5, mice exhibit an aberrant, rightward directed pulmonary artery unlike wild-type mice

embryo
• severe in 95% of mice with remaining mice exhibiting a weaker phenotype
• at E17.5, yolk sacs are filled with blood and local effusion unlike in wild-type mice

growth/size/body
• in less than 5% of mice

respiratory system
• irregularly shaped at E17.5
• at E17.5
