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

limbs/digits/tail
• variable limb defects, with the most severe mutants having a missing autopod, fibula and distal tibia
• 26% of mice have a missing left autopod and an intact right autopod
• 63% of mice exhibit malformed autopods
• 63% of mice have substantial autopod elements on both hindlimbs, although usually with missing/malformed digits
• in forelimbs, commonly one or two anterior digits are absent
• in forelimbs, the radius is sometimes missing, but more commonly one or two anterior digits are absent
• in forelimbs, the radius is sometimes missing
• left hindlimb is usually most severely affected
• in most severely affected mutants
• in most severely affected mutants
• 2 of 19 mutants have severe truncations in both hindlimbs

skeleton
• in forelimbs, the radius is sometimes missing
• in most severely affected mutants
• in most severely affected mutants
