mortality/aging
• almost all die within 48 hours of birth
|
• survival is normal until E14.5 and about 1/3 of homozygotes die before birth
|
embryo
• abnormal left-right patterning of the lungs, liver stomach, intestines, spleen, pancreas, kidneys, adrenal glands, heart, and great vessels
|
growth/size/body
• seen in all homozygotes
|
• about 50% have right-sided stomach, pancreas, and spleen and reversed rotational direction of the intestines
|
liver/biliary system
• liver lobes display reversed left-right asymmetry or are bilaterally symmetrical with 2 equal sized lobes beneath a fused medial lobe
|
renal/urinary system
• the left kidney and adrenal gland are positioned either more cranially or at the same rostral caudal level as the right kidney
|
cardiovascular system
• persistent left vena cava
|
• seen in all homozygotes
|
dextrocardia
(
J:60755
)
• randomized position of the apex resulting in dextrocardia in some mutants
|
• common atrioventricular canal
|
immune system
• severely malformed
|
hematopoietic system
• severely malformed
|
respiratory system
• seen in all homozygotes
|
endocrine/exocrine glands
