Albinism – Causes and Symptoms of Albinism
Albinism is an inherited disease that has damaged one or more genes which are responsible to direct the skin and eyes to produce melanin (pigment). A child’s skin, hair and eyes may be colorless as there is no pigment formation. The inherited genes do not make the normal amounts needed for the development of the retina. Visual impairment is also seen due to lack of melanin in the development of the retina.
- In the United States of America, it is estimated that atleast 1 person out of 17,000 suffer from albinism.
- Albinism affects people from all the races.
What causes Albinism?
The causes of albinism includes the following:
- Genetic factor is the only cause for this disease.

- The defect is transmitted through families.
Types of Albinism
There are two types of albinism. They are:
- Type-1 albinism is caused by the affect on the production of the pigment melanin.
- Type-2 albinism occurs due to the defect in the “P” gene.
- People suffering with this condition have slight coloring at the time of birth.
