Cystic fibrosis: A disease that results from a decrease in fluid and salt secretion by a transport protein known as Cystic Fibrosis Transmembrane Regulator (CFTR). As a result of this defect secretion from the pancreas is blocked and heavy dehydrated mucus accumulates in the lungs leading to chronic lung infection. 

Albinism: It is a recessive disorder due to non-conversion of typosine into melanin because of gene mutation. 

Albinism are of two types : 

• Type 1 albinism is caused by defects that affect production of the pigment, melanin. 

• Type 2 albinism is due to a defect in the ‘P” gene. People with this type have slight coloring at birth.
