autosomal dominant

Autosomal dominance is a pattern of inheritance characteristic of some genetic diseases. Autosomal means that the gene in question is located on one of non-sex chromosomes. Dominant means that a single copy of the disease-associated mutation is enough to cause the disease. This is in contrast to a recessive disorder, where two copies of the mutation are needed to cause the disease. Huntington’s disease is a common example of an autosomal dominant genetic disorder
