Limb abnormalities and edema in Tbx3tm2Moon/Tbx3tm1.1Moon hypomorphs

mortality/aging
• most mice die between E13.5 and E15.5
• no mice survive to birth
• most mice die between E13.5 and E15.5

cardiovascular system
• cardiac conduction system hypoplasia without a change in cell proliferation or apoptosis
• rare ventricular-arterial mal-alignment
• large interventricular foramina in most mice at E13.5 to E14.5
• at E10.5 to E12.5
• atrial arrhythmia at E11.5 to E14.5
• first detected at E11.5 and in most mice at E12.5

limbs/digits/tail
• authors state that mice exhibit limb abnormalities similar to Tbx3tm1Pa homozygotes

embryo
N
• mice exhibit normal yolk sacs and placenta

muscle
• cardiac conduction system hypoplasia without a change in cell proliferation or apoptosis
