Phenotypes Associated with This Genotype

Genotype
MGI:3047099

• Allelic Composition: Fanca^tm1.1Wong/Fanca^tm1.1Wong
• Genetic Background: involves: C57BL/6

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

cellular

decreased germ cell number ( J:85108 )

• ~50% the number of germ cells as wild-type embryos at E11.5

• depletion due to impaired survival or proliferation rather than to impaired migration

abnormal cell physiology ( J:85108 )

• increased susceptibility of cultured bone marrow cells to mitomycin C (MMC), a DNA cross-linking agent

craniofacial

abnormal cranium morphology ( J:85108 )

• mostly involving dextral deviation of the rostrum

• Background Sensitivity: observed on a C57BL/6 genetic background in conjunction with microphthalmia

endocrine/exocrine glands

seminiferous tubule degeneration ( J:85108 )

♂ • Background Sensitivity: 68% were severely degenerated, on a C57BL/6 genetic background

decreased testis weight ( J:85108 )

♂ • Background Sensitivity: reduced testicular weight on a C57BL/6 genetic background relative to heterozygotes and homozygotes on a 129S6/SvEvTac genetic background

growth/size/body

embryonic growth retardation ( J:85108 )

• Background Sensitivity: observed on a C57BL/6 genetic background

decreased body weight ( J:85108 )

• Background Sensitivity: mice on a C57BL/6 genetic background weighed less at birth, indicating retarded prenatal growth

reproductive system

decreased germ cell number ( J:85108 )

• ~50% the number of germ cells as wild-type embryos at E11.5

• depletion due to impaired survival or proliferation rather than to impaired migration

seminiferous tubule degeneration ( J:85108 )

♂ • Background Sensitivity: 68% were severely degenerated, on a C57BL/6 genetic background

decreased testis weight ( J:85108 )

♂ • Background Sensitivity: reduced testicular weight on a C57BL/6 genetic background relative to heterozygotes and homozygotes on a 129S6/SvEvTac genetic background

reduced female fertility ( J:85108 )

♀

skeleton

abnormal cranium morphology ( J:85108 )

• mostly involving dextral deviation of the rostrum

• Background Sensitivity: observed on a C57BL/6 genetic background in conjunction with microphthalmia

vision/eye

microphthalmia ( J:85108 )

• often observed in conjunction with craniofacial abnormalities

• Background Sensitivity: exhibited by ~30% of mice on a C57BL/6 genetic background

embryo

embryonic growth retardation ( J:85108 )

• Background Sensitivity: observed on a C57BL/6 genetic background
