ht1

• Allelic Composition: Del(5D5Mit73-D5Mit351)5Jcs/+
• Genetic Background: involves: 129S4/SvJae * C3H * C57BL/6J

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

growth/size/body

decreased body weight ( J:67077 )

• Background Sensitivity: the severe runting is less severe as the deletion is backcrossed onto the C3H background
