hm1

• Allelic Composition: sno/sno
• Genetic Background: involves: K/Gw

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

craniofacial

short snout ( J:5675 )

• recognizeable at 2 weeks of age

skeleton

abnormal vertebral column morphology ( J:5675 )

• there is variation from nearly normal closure to trough-like

abnormal thoracic vertebrae morphology ( J:5675 )

kyphosis ( J:5675 )

• occurs occasionally and not in a specific area

small sacral vertebrae ( J:5675 )

abnormal vertebral arch morphology ( J:5675 )

• incudes the lumbar and often posterior thoracic and sacral vertebrae

spina bifida occulta ( J:5675 )

• occurs with variable severity in the lumbar and/or in the posterior thoracic and sacral vertebrae

nervous system

spina bifida occulta ( J:5675 )

• occurs with variable severity in the lumbar and/or in the posterior thoracic and sacral vertebrae

limbs/digits/tail

abnormal tail position or orientation ( J:5675 )
