behavior/neurological
craniofacial
• various dysmorphology can occur
• more frequent in homozygotes
|
digestive/alimentary system
• imperforate rectum possible
|
hearing/vestibular/ear
limbs/digits/tail
• reduction in hind leg may occur
• more frequent in homozygote
|
• mitotic gene conversion events during early development produce mosaicism, an explanation for variable tail phenotype expression
|
short tail
(
J:12953
)
• homozygotes are likely to have shorter tails than heterozygotes
|
• homozygotes are more likely to have bifurcated tails than heterozygotes
|
renal/urinary system
absent kidney
(
J:12953
)
• one or both kidneys and ureters may be missing
|
absent ureter
(
J:12953
)
• one or both kidneys and ureters may be missing
|
• imperforate urethra possible
|
skeleton
• various dysmorphology can occur
• more frequent in homozygotes
|
absent ribs
(
J:12953
)
• number absent and frequency of absence is variable
|
rib fusion
(
J:12953
)
• number of ribs fused and location are variable
|
cellular
• offspring of homozygous or heterozygous Axin1Fu mothers are less likely to express abnormalities than offspring of homozygous wild-type mothers
