Genetics professor Valdir Balbino of the Federal University of Pernambuco said this is a very rare occurrence considering the parents and two other children are black.
Both parents must carry the albinism gene in order to produce a child with albinism. Where both parents are carriers of the albinism gene, there is a one in four chance that a child will be born with the condition.
The family live in the slum of Olinda in north-east Brazil and the children have faced taunts by fellow pupils at their school.
The condition affects around one in 17,000 people. Those with albiinism do not produce enough melanin pigment, which gives colour to the skin, hair and eyes and protects the body from the sun's rays.
They often suffer from extreme short-sightedness and a severe sensitivity to light.
