Find Mice Using the International Mouse Strain Resource (IMSR)
Mouse lines carrying:
Hap1tm2Id mutation (0 available); any Hap1 mutation (37 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• most mutants die by P3 with only 8% surviving to 2 weeks and most of these dying before weaning

behavior/neurological
• mutants have a normal rooting reflex but an increased latency time for attachment to the nipple and more mutants fail to attach to the nipple
• no milk is seen in mutant stomachs

growth/size/body
• mutants that survive to 2 weeks show a 70% reduction in body size
