When these structures are inactivated, they can become Barr bodies, and intellectual disability is associated with its namesake "fragile" syndrome.
Defects in the MCCS unit in this structure is connected with microphthalmia with linear skin defects. The Sherman paradox describes how a disease related to this structure seems to appear more commonly in later generations. An irregular representation of these structures leads to their namesake "mosaicism." Tsix [tee- six] is an antisense gene that that methylates the promoter of a gene that coats this structure. That latter gene is a "specific (*) transcript" partially named for this structure. In a disease associated with this structure, CGG repeats affect the FMR1 gene, which can potentially cause mental retardation. These structures can be packaged into the form of facultative heterochromatin in a process called lyonization. When these structures are inactivated, they can become Barr bodies, and intellectual disability is associated with its namesake "fragile" syndrome. For 10 points, name this sex chromosome that females contain two of but males only contain one of.
