Cystic fibrosis (CF) Cystic fibrosis is one of the most common inherited single gene disorders in Caucasians. However, if only one abnormal gene is needed to produce a disease, it leads to a dominant hereditary disorder.

Autosomal recessive is a pattern of inheritance characteristic of some genetic disorders. Glycogen storage disease type III. These are also used to determine any Hereditary gene which can be passed on to children leading to passing on the disorder from parent to child. Introduction: A large number of genes involved in autosomal recessive forms of intellectual disability (ID) were identified over the past few years through whole-exome sequencing (WES) or whole-genome sequencing in consanguineous families. Two copies of an abnormal gene—one from each parent—must be present for an autosomal recessive disease to develop. Cystic Fibrosis.
