What are the Symptoms?
This symptoms of Chondrodysplasia Punctata are pretty easily recognized. The X-linked recessive form of this condition does affect both sexes however, the symptoms experienced by females tend to be less pronounced than the symptoms experienced by males. The symptoms of this disorder include patches of dry and coarse hair, growth retardation, large pores, shortening of limbs, scaly and dry skin and cataracts. In some cases, children with this disorder can become mildly retarded.
Diagnosing this disorder is relatively easy. The doctor will first take a complete family medical history and ask about the child's symptoms. They will then perform a complete physical exam. Once these are done they will draw blood to check the child's plasmalogen levels. If the plasmalogen levels are extremely low, the child has this disorder. A skin biopsy will them be performed to determine what type of this condition the child has.
How is This Disorder Treated?
