18. gatbonton dwarfism

  1. 1. DWARFISM(ACHONDROPLASIA)
  2. 2. ACHONDROPLASIA Literally means “without cartilage formation” Most common type of dwarfism. Caused by mutation of gene for (FGFR3) Average height is about 4 ft. Short arms and legs. Large head.
  3. 3.  Achondroplasia is one of a group of disorders calledchondrodystrophies or osteochondrodysplasias. May be inherited as an autosomal dominant trait, which means thatif a child gets the defective gene from one parent, the child will havethe disorder.
  4. 4. SIGNS AND SYMPTOMS Abnormal hand appearance with persistent space between the longand ring fingers Bowed legs Decreased muscle tone Disproportionately large head-to-body size difference Prominent forehead
  5. 5.  Shortened arms and legs (especially the upper arm and thigh) Short stature (significantly below the average height for a personof the same age and sex) Spinal stenosis Spine curvatures called kyphosis and lordosis
  6. 6. DENTAL CORRELATION The administration of thyroid hormone is known to acceleratedental development and eruption His dental development is still extremely retarded and isfollowing a disturbed pattern in which various stages of dentaldevelopment are present simultaneously
  7. 7. SINGLE GENE It is considered as single gene because only the Fibroblast GrowthFactor Receptor Gene 3 is affected which is also important in themaintenance of bone and brain tissues
