Any chromosome other than a sex chromosome [1], or allosome or is not involved in sex determination. In humans there are 22 pairs of autosomal chromosomes. Sex chromosomes determine the early stages of female and male development, whereas autosomal chromosomes contain many genes regarding development later on within the genome [2].

Autosomal diseases are a type of genetic disease that can be classed into autosomal dominant or autosomal recessive disorders.

Examples of an autosomal dominant disease is Huntington's Disease. Furthermore, examples of autosomal recessive disorders are Cystic fibrosis and Sickle cell anaemia.
