General annotation (Comments)

Tissue specificity

Brain (most abundant in hippocampus and amygdala), placenta and lung.

Involvement in disease

Defects in AFF2 are the cause of FRAXE [MIM:309548]. FRAXE is an X-linked form of mental retardation. Loss of FMR2 expression is correlated with FRAXE CCG(N) expansion. Normal individuals have 6-35 copies of the repeat, whereas cytogenetically positive, developmentally delayed males have more than 200 copies and show methylation of the associated CPG island.

Sequence similarities

Belongs to the AF4 family.
