Fragile X syndrome Orphanet: The expansion is associated with hypermethylation of the repetitive area and the adjacent CpG island, which entails a lack of gene transcription and an absence of protein FMRPthis absence being the ultimate cause of the syndrome.


Transitions from one fragli to another can be difficult for children with FXS. Who can be an associate? If the mutation expands they will inherit the full mutation and will be affected. FXS is characterized by social anxietyincluding poor eye contact, gaze aversion, prolonged time to commence social interaction, and challenges forming peer relationships. The diagnosis of FXS has evolved from karyotype with special culture medium, to molecular techniques that are more sensitive and specific including PCR and Southern Blot.
