N normal phenotype
cardiovascular system
heart hypoplasia ( J:131577 )
• mice exhibit smaller hearts than mice homozygous for null alleles of Fgfr1 and Fgfr2 due to decreased myocardial proliferation
• however, coronary development is normal
thin ventricular wall ( J:131577 )
• mice exhibit thinner ventricular walls than mice homozygous for null alleles of Fgfr1 and Fgfr2
