2. What is the inheritance patterns?Can exhibit autosomal dominant or recessive inheritance, with genetic heterogeneity
3. What is the associated ocular features?May include axial elongation, altered corneal curvature, or lens abnormalities
4. Why do people with this syndrome have extra digits?It happens because genes that control how fingers and toes grow are changed, which can make extra digits form.
5. How does the syndrome affect a person's eyesight?It makes the eye longer or changes the shape of the cornea or lens, so the person sees close objects clearly but far ones are blurry.
