Mouse lines carrying:
Hoxa2tm1Fmr mutation (0 available); any Hoxa2 mutation (21 available)
♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
mortality/aging
lethality at weaning, complete penetrance ( J:80131 )
• mice die at three weeks of age

craniofacial
abnormal styloid process morphology ( J:80131 )
• at E18.5, some mice exhibit unilateral abnormalities in the styloid process
abnormal hyoid bone lesser horn morphology ( J:80131 )
• at E18.5, some mice exhibit unilateral abnormalities in the lesser horns of the hyoid bone
abnormal stapes morphology ( J:80131 )
• at E18.5, some mice exhibit unilateral abnormalities in the stapes

growth/size/body
postnatal growth retardation ( J:80131 )

hearing/vestibular/ear
abnormal stapes morphology ( J:80131 )
• at E18.5, some mice exhibit unilateral abnormalities in the stapes

nervous system
abnormal rhombomere 2 morphology ( J:80131 )
• segmentation and patterning of rhombomere 2 is disrupted as determined by marker expression patterns
• however, patterning of rhombomere 3 is normal

skeleton
abnormal styloid process morphology ( J:80131 )
• at E18.5, some mice exhibit unilateral abnormalities in the styloid process
abnormal hyoid bone lesser horn morphology ( J:80131 )
• at E18.5, some mice exhibit unilateral abnormalities in the lesser horns of the hyoid bone
abnormal stapes morphology ( J:80131 )
• at E18.5, some mice exhibit unilateral abnormalities in the stapes

embryo
abnormal rhombomere 2 morphology ( J:80131 )
• segmentation and patterning of rhombomere 2 is disrupted as determined by marker expression patterns
• however, patterning of rhombomere 3 is normal
