American Journal of Intellectual and Developmental Disabilities, 277— Surgery or patching are usually necessary to treat strabismus if diagnosed early.
CGG repeats between 53 and set the pre-mutation which is not accompanied by clinical signs but it is very unstable and can grow to full mutation over CGG repeats when it is transmitted by a female to the next generation. Newborn screening and cascade testing for FMR1 mutations.
Brain and Cognition, 82 184— Speech may be cluttered or nervous. However, there is some evidence that standardized IQ decreases over time in the majority of cases, apparently as a result of slowed intellectual development. Literature Non-fiction The Accidental Teacher: Individuals with FXS present with intellectual disability, autism, hyperactivity, long face, large or prominent ears and macroorchidism at puberty and thereafter.
The pre-mutation can be unchanged for several generations, or switch to full mutation in one generation, but the change always happens through a woman. Supplemental Content Full text links.

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.

Given the genomic features of the syndrome, there are patients with a number of triplet repeats between 55 andknown as premutation carriers.

Early diagnosis of fragile X syndrome or carrier status is important for providing early intervention in children or fetuses with the syndrome, and allowing genetic counselling with regards to the potential for a couple’s future children to be affected. Exert the frsgil that confer them in each case. Frabil CGG triplet is polymorphic in the general population ranging from 6 to 52 repeats.
