hm1

• Allelic Composition: Hoxa5^tm1Ljea/Hoxa5^tm1Ljea
• Genetic Background: involves: 129/Sv * C57BL/6J * SJL

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

mortality/aging

neonatal lethality, incomplete penetrance ( J:125040 )

• mortality occurs at birth with fewer than expect mice survive to weaning

• however, surviving mice are viable, fertile and present no phenotypic abnormalities

respiratory system

atelectasis ( J:125040 )

• at E18.5, mice present with collapsed lungs

abnormal tracheal cartilage morphology ( J:125040 )

• all mice have abnormal trachea with fusion of the first tracheal rings to the cricoid, an abnormal banding pattern of the rings and a reduced dorsal extension of the cartilage along the trachea

cricoid and tracheal cartilage fusion ( J:125040 )

• fusion of the first tracheal rings to the cricoid

skeleton

abnormal tracheal cartilage morphology ( J:125040 )

• all mice have abnormal trachea with fusion of the first tracheal rings to the cricoid, an abnormal banding pattern of the rings and a reduced dorsal extension of the cartilage along the trachea

cricoid and tracheal cartilage fusion ( J:125040 )

• fusion of the first tracheal rings to the cricoid

abnormal cervical vertebrae morphology ( J:125040 )

• at E18.5, the tuberculum anterior on C6 is absent in nearly all mice bilaterally

• at E18.5, ribs are present on C7 bilaterally in 7 of 13 mice and unilaterally in 5 of 13 mice compared to wild-type mice in which ribs are absent bilaterally in nearly all mice

• at E18.5, ectopic dorsal processes are present on T1 in all mice as opposed to 50% of wild-type mice
