ht2
Allelic
Composition		 Fasntm1Schi/Fasn+
Genetic
Background		 involves: 129S7/SvEvBrd * C57BL/6J
Find Mice Using the International Mouse Strain Resource (IMSR)
Mouse lines carrying:
Fasntm1Schi mutation (0 available); any Fasn mutation (89 available)
♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
mortality/aging
prenatal lethality, incomplete penetrance ( J:83624 )
• Background Sensitivity: 60-70% loss of pups on a mixed background involving 129S7/SvEvBrd and C57BL/6J
• feeding breeders a diet rich in saturated fatty acids does not prevent lethality of heterozygotes
