What is the official name of the ASPM gene?
The official name of this gene is “abnormal spindle microtubule assembly.”
ASPM is the gene's official symbol. The ASPM gene is also known by other names, listed below.

What is the normal function of the ASPM gene?
The ASPM gene provides instructions for making a protein that is involved in cell division. This protein is found in cells and tissues throughout the body; however, it appears to be particularly important for the division of cells in the developing brain. Studies suggest that the ASPM protein helps maintain the orderly division of early brain cells called neural progenitor cells, which ultimately give rise to mature nerve cells (neurons). By promoting the division of neural progenitor cells during early brain development, the ASPM protein helps determine the total number of neurons and the overall size of the brain.
How are changes in the ASPM gene related to health conditions?
Genetics Home Reference provides information about age-related macular degeneration, which is also associated with changes in the ASPM gene.
Where is the ASPM gene located?
Cytogenetic Location: 1q31
Molecular Location on chromosome 1: base pairs 197,084,127 to 197,146,694
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The ASPM gene is located on the long (q) arm of chromosome 1 at position 31.
More precisely, the ASPM gene is located from base pair 197,084,127 to base pair 197,146,694 on chromosome 1.
