Female Carriers


The ABCD1 gene is located on the X-chromosome. Women have two X chromosomes. In women who carry the ALD gene mutation on one X-chromosome, the full-blown disease does not appear because there is a normal copy of the gene on the other X-chromosome. But women can pass the gene to their children, hence the term ‘carrier’.

There is more information about ALD and AMN on our website.
