In regards to ATR-X syndrome, you describe how abnormal chromatin remodeling is a result of a genetic mutation in the gene, ATRX. What does this gene encode for? What group, acetyl, methyl, or phosphate, is thought to be involved in this condition? You will find that they do not think there is a direct link between the gene and the modifying group, meaning that the gene is not responsible for adding or removing the group from the chromatin. Therefore, what do they suspect is the relationship between the two?
