Failure of eyelid closure, enlarged aortic, pulmonic, and tricuspid heart valves, and enlarged zone of hypertrophic chondrocytes in growth plates of Rhbdf1^{tm1b(EUCOMM)Wtsi}/Rhbdf1^{tm1b(EUCOMM)Wtsi} Rhbdf2^tm1Mak/Rhbdf2^tm1Mak (iR1/2-/-) and Adam17^tm1.1Bbl/Adam17^tm1.1Bbl mice.

mortality/aging

perinatal lethality ( J:221411 )

• mice are born at the expected Mendelian ratio but show perinatal lethality

vision/eye

failure of eyelid fusion ( J:221411 )

• mice exhibit failure of eyelid closure

eyelids open at birth ( J:221411 )

• mice are born with open eyes

cardiovascular system

thick tricuspid valve cusps ( J:221411 )

• at P1, tricuspid valve leaflets are thickened in relationship to their length

enlarged tricuspid valve ( J:221411 )

• newborn (P1) mice display enlarged tricuspid heart valves

• however, mitral valves are normal

thick aortic valve cusps ( J:221411 )

• newborn (P1) mice show a significant increase in the average width relative to the length of individual aortic valve leaflets

enlarged aortic valve ( J:221411 )

• newborn (P1) mice display enlarged aortic heart valves

thick pulmonary valve cusps ( J:221411 )

• at P1, pulmonic valve leaflets are thickened in relationship to their length

enlarged pulmonary valve ( J:221411 )

• newborn (P1) mice display enlarged pulmonic heart valves

skeleton

increased width of hypertrophic chondrocyte zone ( J:221411 )

• newborn (P1) mice display an enlarged zone of hypertrophic chondrocytes in the femoral and humoral growth plates
