ASPM is a gene located on human chromosome 1, band q31 (1q31) which is associated with autosomal recessive primary microcephaly (smaller then average sized head).
"ASPM" is an acronym for "Abnormal Spindle-like, Microcephaly-associated", According to researchers the ASPM gene variation arose about 5,800 years ago, roughly correlating with the development of written language, spread of agriculture and development of cities.

Researchers are considering the ASPM gene a major factor in the development (and therefore size) of the human brain.
A mutation in ASPM causes a disorder called familial microcephaly (literally, "small head", and literally, these individuals have small heads and brains). This disorder also causes moderate-to-profound mental retardation.
