renal/urinary system
• in tubules distal to the proximal tubules, cilia are shorter compared to wild-type cells (1.0+/-0.6 and 1.3+/-0.6 compared to 3.1+/-1.4 and 3.5+/-1.7 at 4 and 7 days of age, respectively)
|
endocrine/exocrine glands
• increased dilation of duct-like structures and pancreatic lobules are separated by increased interstitial space as well as increased number of tubular complexes; however the islets of Langerhans are morphologically normal and not reduced in number
|
• the remaining pancreatic cilia are shortened at E15.5, E18.5 and 4 days of age
|
• pancreatic primary cilia are almost absent
|
• progressive loss of acinar cells from birth to 17 days
|
• relative to acinar and beta-cells a 3-fold increase in ductal cell proliferation is seen
|
• loss of acinar cells results in severe reduction in pancreatic mass
|
pancreas cyst
(
J:90990
)
• by 2 weeks of age large pancreatic cyst is seen and at E18.5, intracinar ducts are slightly dilated
|
• shortly after birth amylase expression is increased; however glucose tolerance is normal
|
limbs/digits/tail
• at E12.5, minor expansion of the limb bud is seen mainly on the anterior side
|
• carpals are fused or malformed in many mice
|
• phalange 2 of digits II and V is severely reduced in length or absent
|
polydactyly
(
J:83305
)
• in the forelimbs polydactyly is often seen as a fusion with digit I and in the hindlimbs polydactyly is a complete duplication with both phalanges resembling digit I
|
• tarsals are fused or malformed in many mice
|
craniofacial
• the parietal and frontal sutures are disorganized and fail to fuse
|
• mice have 4 rather than 3 molars on both the upper and lower jaws with the extra molar composed of a single cuspid and rostral to what is normally the first molar
|
• minor clefting of the palatine process
|
hearing/vestibular/ear
• the opening in the perioctic capsule is absent
|
skeleton
• the parietal and frontal sutures are disorganized and fail to fuse
|
• mice have 4 rather than 3 molars on both the upper and lower jaws with the extra molar composed of a single cuspid and rostral to what is normally the first molar
|
• carpals are fused or malformed in many mice
|
• tarsals are fused or malformed in many mice
|
• the tibia and fibula fail to fuse
|
• phalange 2 of digits II and V is severely reduced in length or absent
|
digestive/alimentary system
• minor clefting of the palatine process
|
• progressive loss of acinar cells from birth to 17 days
|
• relative to acinar and beta-cells a 3-fold increase in ductal cell proliferation is seen
|
embryo
• at E12.5, minor expansion of the limb bud is seen mainly on the anterior side
|
cellular
• in tubules distal to the proximal tubules, cilia are shorter compared to wild-type cells (1.0+/-0.6 and 1.3+/-0.6 compared to 3.1+/-1.4 and 3.5+/-1.7 at 4 and 7 days of age, respectively)
|
• the remaining pancreatic cilia are shortened at E15.5, E18.5 and 4 days of age
|
• pancreatic primary cilia are almost absent
|
growth/size/body
• mice have 4 rather than 3 molars on both the upper and lower jaws with the extra molar composed of a single cuspid and rostral to what is normally the first molar
|
• minor clefting of the palatine process
|
pancreas cyst
(
J:90990
)
• by 2 weeks of age large pancreatic cyst is seen and at E18.5, intracinar ducts are slightly dilated
