Fragile X Syndrome (FXS) is the most common inherited cause of intellectual disability and autism. It results from a mutation in the FMR1 gene on the X chromosome, leading to a deficiency in the fragile X mental retardation protein (FMRP), which is crucial for normal neural development. Interestingly, the severity of symptoms can vary widely among individuals, with males typically being more affected than females due to the presence of only one X chromosome.
