Inherited autosomal dominant
WebbKey messages. An autosomal dominant condition only requires one copy of a gene to be altered for the condition to present. The chance of a child inheriting the variant (and developing the condition) from an affected parent is 1 in 2 (50%). Incomplete penetrance can occur when not everyone who has the pathogenic variant develops the disease, for ...
