Allelic
Composition		 Fasntm1Schi/Fasntm1Schi
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 (88 available)
♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
mortality/aging
embryonic lethality before implantation, complete penetrance ( J:83624 )
• death at the blastocyst stage, most dying before E3.5
• feeding breeders a diet rich in saturated fatty acids does not prevent lethality of homozygotes
