What is the Achondrplasia Disorder?
a hereditary condition where the growth of long bones that contain cartilage is retarded, producing very short limbs and sometimes a face that is small but has a normal sized skull.
- During early stages of babies growth development most of the skeleton is made up of cartilage. Normally the cartilage would change into bone but in babies with dwarfism there cartilage will not change. It causes Mutation in the body
- Abnormal hand appearance withspace between the long and ring fingers
- Bowed legs
- Decreased muscle tone
- Disproportionately large head to body size difference
- Prominent forehead
- Shortened arms and legs
- Short stature
- Spinal stenosis
- Spine curvatures
Why do people have Dwarfism?
How is Achrondroplasia inherited?
Is the a treated for the disorder?
How is the disorder diagnosed?
During pregnancy a ultrasound before the birth may show excessive amniotic fluid surrounding the unborn baby. Examination of the baby after birth shows increased front to back head size. There may be signs of hydrocephalus ( water on the brain ). X-rays of the long bones can reveal achondroplasia in the newborn.
