Autosomal Dominant Disorder
An Autosomal Dominant Disorder is a type of genetic disorder that is caused by a mutation in a gene located on one of the 22 pairs of autosomal chromosomes. The term "dominant" refers to the fact that only one copy of the mutated gene, inherited from either parent, is necessary to have the disorder.
Pronunciation
The term is pronounced as aw-toh-soh-muhl doh-muh-nuhnt dis-ord-er.
Etymology
The term "Autosomal Dominant Disorder" is derived from three words. "Autosomal" comes from the Greek word "autos" meaning self and "soma" meaning body. "Dominant" is derived from the Latin word "dominans" meaning ruling or governing. "Disorder" comes from the Latin word "disordinare" meaning to throw into disorder.
