What is the official name of the AAAS gene?

The official name of this gene is “aladin WD repeat nucleoporin.”

AAAS is the gene's official symbol. The AAAS gene is also known by other names, listed below.

Read more about gene names and symbols on the About page.

What is the normal function of the AAAS gene?

The AAAS gene provides instructions for making a protein called ALADIN whose function is not well understood. Within cells, ALADIN is found in the nuclear envelope, the structure that surrounds the nucleus and separates it from the rest of the cell. Based on its location, ALADIN is thought to be involved in the movement of molecules into and out of the nucleus.

Does the AAAS gene share characteristics with other genes?

The AAAS gene belongs to a family of genes called WDR (WD repeat domain containing).

A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.

How are changes in the AAAS gene related to health conditions?

triple A syndrome - caused by mutations in the AAAS gene

At least 49 mutations in the AAAS gene have been found to cause triple A syndrome. These mutations change the structure of ALADIN in different ways; however, almost all mutations prevent this protein from reaching its proper location in the nuclear envelope. The absence of ALADIN likely disrupts the movement of molecules across this membrane. Researchers suspect that DNA repair proteins may be unable to enter the nucleus if ALADIN is missing from the nuclear envelope. DNA damage that is not repaired can cause the cell to become unstable and lead to cell death. Although the nervous system is particularly vulnerable to DNA damage, it remains unknown exactly how mutations in the AAAS gene lead to the signs and symptoms of triple A syndrome.

Where is the AAAS gene located?

Cytogenetic Location: 12q13

Molecular Location on chromosome 12: base pairs 53,307,456 to 53,321,628

(Homo sapiens Annotation Release 107, GRCh38.p2) (NCBIThis link leads to a site outside Genetics Home Reference.)

The AAAS gene is located on the long (q) arm of chromosome 12 at position 13.

The AAAS gene is located on the long (q) arm of chromosome 12 at position 13.

More precisely, the AAAS gene is located from base pair 53,307,456 to base pair 53,321,628 on chromosome 12.
