Reason:

Chromosome dominant inheritance is mainly due to the formation of epiphyseal chondrocytes in long bones, which affects the length of bones and makes them thicker rather than grow. The child's limbs are thick and short, but the trunk is dominant, so the length of the upper body is longer than that of the lower body, and the hand cannot be hung over the hip joint.

Short fingers, flush fingers, low nose, large head circumference, protruding forehead, protruding abdomen, protruding lumbar vertebrae, protruding buttocks, and normal intelligence. X-ray examination of long bone shows that the long bone becomes shorter, the curvature increases and the ends increase.

Children often have short stature, special face, low intelligence, low nose, wide eye distance, eyes facing outwards, mouth half open, tongue sticking out, palm prints running through, little finger bending inward, and sometimes congenital heart disease. Chromosome analysis can confirm the diagnosis.
