hm1

• Allelic Composition: Gapdh^m4Neu/Gapdh^m4Neu
• Genetic Background: C3.Cg-Gapdh^m4Neu

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

mortality/aging

embryonic lethality between implantation and somite formation, incomplete penetrance ( J:126359 )

• number of live implantations is reduced by around 32%, compared to wild-type, suggesting lethality occurs shortly after implantation

Genotype
MGI:3663929

hm2

• Allelic Composition: Gapdh^m4Neu/Gapdh^m4Neu
• Genetic Background: involves: 101/El * C3H/El

mortality/aging

preweaning lethality, complete penetrance ( J:11216 , J:15476 )

• homozygotes are not detected but time point of examination is not given (J:15476)

Genotype
MGI:3808734

ht3

• Allelic Composition: Gapdh^m4Neu/Gapdh⁺
• Genetic Background: C3.Cg-Gapdh^m4Neu

mortality/aging

preweaning lethality, incomplete penetrance ( J:126359 )
