1 Single gene disorders are caused by a mutation in a single gene. 2  The mutation may be present on one or both chromosomes (one chromosome inherited from each parent). 3  Sickle cell disease, cystic fibrosis and gCJD are examples of single gene disorders.
Hereditary diseases are caused primarily by chromosomal and gene mutations; a distinction is made, accordingly, between chromosomal and strictly hereditary (gene) diseases. Mutation results in the disruption of the synthesis of a particular polypeptide (structural protein or enzyme).ereditary diseases are caused primarily by chromosomal and gene mutations; a distinction is made, accordingly, between chromosomal and strictly hereditary (gene) diseases.
