mortality/aging
• all die within 24 hours after birth
|
craniofacial
• 3 of 3 show deficient formation of the supraoccipital bone resulting in a misshapen bone with or without cartilage formation bridging the 2 halves of the bone at the midline
|
cleft palate
(
J:28713
)
• seen in 50% of mutants
|
skeleton
• 3 of 3 show deficient formation of the supraoccipital bone resulting in a misshapen bone with or without cartilage formation bridging the 2 halves of the bone at the midline
|
• 1 of 3 exhibits severely deficient formation of the 4th and 5th sternebrae, both of which are dumbbell-shaped, and mildly misshapen 2nd and 3rd sternebrae
|
• 1 of 3 shows slight misalignment of the 5th and 6th pairs of ribs resulting in the abnormalities of the 4th and 5th sternebrae
|
• 1 of 3 shows a malformation in the axis (second cervical vertebra), with the right half of the axis incompletely developed with lack of formation of the more anterior part close to the midline resulting in abnormal articulation between bone and cartilage on that side
