mortality/aging
• about 42% of the pups with the conditional knockout genotype are found dead at birth
• normal Mendelian ratios are found at E18.5

respiratory system
• at E18.5, lungs display collapsed morphology similar to that observed for Hoxa5tm1Rob homozygotes
• enlargement of alveolar spaces is observed in surviving mice at P30, similar to that observed in Hoxa5-/- animals
• severe disorganization of the trachea is observed in E18.5 skeletons
• pups display respiratory distress at birth at birth

skeleton
• process is misshapen at E18.5
• extra ribs on cervical vertebra 7 (C7) are observed at E18.5
• absent or shorter tuberculum anterior are observed on C6 at E18.5
