Autosomal dominant inheritance refers to a pattern of genetic transmission where a single copy of a mutated gene from an affected parent can cause a disease. In this mode of inheritance, the mutated gene is located on one of the autosomes (non-sex chromosomes), and only one altered copy of the gene is necessary to increase the risk of developing a particular condition, such as cancer. This means that a person with an autosomal dominant cancer predisposition has a 50% chance of passing the mutated gene to each of their offspring.
