Question

Quizplus · Accepted Answer

Fragile X syndrome is caused by a mutation in the FMR1 gene on the X chromosome, leading to an overproduction of the protein FMRP, which is important for neural development and synaptic plasticity. Males with Fragile X syndrome show a particular pattern of cognitive functioning, with weaknesses in sequential processing of information but strengths in simultaneous, holistic processing. This is thought to be due to dysfunction in the prefrontal cortex, which is involved in working memory and executive functioning, and the parietal cortex, which is involved in spatial processing and attention. Females with Fragile X syndrome may also show similar cognitive patterns but to a lesser degree, as they have two X chromosomes and one may compensate for the affected gene on the other.
