Are metabolic disorders contagious and can one siblings get affected by other?
Metabolic Disorders like any other infections (cough or cold) are not contagious. However, if the parents are carriers of a defective gene, then there is a high possibility that the disorder may be passed on to more than one child in that family. They are not passed on to each other between siblings. Sometime it might look like that as the disease shows signs and symptoms at various ages.
Metabolic disorders are caused by a defective gene leading to faulty enzyme function which is important for metabolism of food component. In this case as the baby grows with faulty metabolism certain compounds gets accumulated in the body leading to abnormal growth and learning pattern.
Metabolic disorders are diagnosed by urine test after birth which acts as a preventive cover for 100 disorders. Early diagnosis leads to early management of the disorders.
