Males with the FMR1 premutation and clinical evidence of FXTAS were found to have increased occurrence of somatizationobsessive—compulsive disorderinterpersonal sensitivity, depression, phobic anxiety, and psychoticism. Social withdrawal behaviors, including avoidance and indifference, appear to be the best predictors of ASD in FXS, with avoidance appearing to be correlated more with social anxiety while indifference was more strongly correlated to severe ASD.

The explanation for this phenomenon is that male carriers pass on their premutation to all of their daughters, with the length of the FMR1 CGG repeat typically not increasing during meiosisthe cell division that is required to produce sperm.
