Which development issue is associated with Fragile X syndrome?

Fragile X syndrome is a genetic condition that commonly leads to developmental issues, particularly affecting speech and language development. Children with Fragile X syndrome often experience delayed speech development, which can manifest as a later onset of talking and difficulties with communication skills throughout their early years. This aspect of the syndrome is linked to the underlying genetics, specifically mutations in the FMR1 gene, which can disrupt normal brain development and functioning.

While some individuals may experience challenges related to motor skills or have varying physical attributes, delayed speech development is a hallmark characteristic directly associated with Fragile X syndrome. This further emphasizes the primary impacts of the condition on a child's cognitive and communicative abilities, rather than issues such as severe vision impairment or advanced physical growth, which are not typical features of the syndrome.
