Rspo2ftls/Rspo2ftls Rspo3tm1.1Jcob/Rspo3tm1.2Jcob Tg(Prrx1-cre)1Cjt/0 double mutants have more severe limb defects than single mutants

mortality/aging
• mice die at birth as do Rspo2ftls homozygotes

limbs/digits/tail
• in the forelimb
• in digits of the forelimbs in 5 of 6 mice; all mice lack 1 digit
• three shortened middle digits
• more subtle than in hindlimbs
• at birth, mice lack most of their hindlimbs
• hindlimb abnormalities are more severe more proximally than in Rspo2ftls homozygotes
• severely shortened and bent in two mice
• severely shortened in two mice
• in one mouse

respiratory system
• as in Rspo2ftls homozygotes

behavior/neurological
• as in Rspo2ftls homozygotes

skeleton
• severely shortened and bent in two mice
• severely shortened in two mice
• in one mouse
