Autosomal Recessive Genetic Features
In autosomal recessive inheritance, two parents have a faulty gene but not the condition linked to it. This is because they both have one healthy gene.
However, their offspring can inherit two copies of the faulty gene. The offspring will have a 25% chance of inheriting two faulty genes.
Inheriting two faulty copies of the following genes, one from each parent, increases the risk of Parkinson’s disease:
- PARK2
- PARK7
- PINK1, or PARK6
- DJ-1
- PRKN
However, inheriting these genes does not still mean for a fact that you’ll develop the condition.
