Phenotypes Associated with This Genotype

Genotype
MGI:7708015

• Allelic Composition: Col17a1^em1Dcr/Col17a1^em1Dcr; Lamc2^jeb/Lamc2^jeb
• Genetic Background: B6.Cg-Lamc2^jeb Col17a1^em1Dcr/Dcr

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

mortality/aging

premature death ( J:352187 )

• the majority of double homozygotes are dead by 10 weeks of age

integument

abnormal nail bed morphology ( J:352187 )

nail dystrophy ( J:352187 )

• separation in the nail bed is found in the double homozygote and requires both alleles

abnormal skin morphology ( J:352187 )

• The junctional epidermolysis bullosa phenotype of the jeb mutation has an earlier onset and more severe phenotype in addition to the novel phenotype of separation of the nail bed, which is not seen in either homozygote in the absence of the other mutation so is unique to the bigenic genotype

dermal-epidermal separation ( J:352187 )

blistering ( J:352187 )

skin detachment ( J:352187 )

decreased skin tensile strength ( J:352187 )

immune system

ear inflammation ( J:352187 )

limbs/digits/tail

ulcerated autopod ( J:352187 )

hearing/vestibular/ear

ear inflammation ( J:352187 )
