About a third of those affected have features of autism such as problems with social interactions and delayed speech. Hyperactivity is common and seizures occur in about 10 percent of the FXS population.<\/p>\n<p>Fragile X syndrome has an X-linked dominant inheritance, typically caused by an expansion of the CGG triplet repeat within the FMR1 (fragile X mental retardation 1) gene on the X chromosome.<\/p>\n<h2><b>Signs of FXS<\/b><\/h2>\n<p>Most young children do not show any physical signs of FXS\u2014 physical features usually begin to develop around the time puberty begins.\u00a0 Aside from intellectual disability, prominent characteristics of the syndrome may include:<\/p>\n<ul>\n<li style=\"font-weight: 400;\">Large, protruding ears<\/li>\n<li style=\"font-weight: 400;\">Long face (vertical maxillary excess)<\/li>\n<li style=\"font-weight: 400;\">High-arched palate (related to the above)<\/li>\n<li style=\"font-weight: 400;\">Hyper-extensible finger joints<\/li>\n<li style=\"font-weight: 400;\">Hyper-extensible (&#8216;double-jointed&#8217;) thumbs<\/li>\n<li style=\"font-weight: 400;\">Post pubescent macro-orchidism<\/li>\n<li style=\"font-weight: 400;\">Hypotonia (low muscle tone)<\/li>\n<li style=\"font-weight: 400;\">Flat feet<\/li>\n<li style=\"font-weight: 400;\">Soft skin<\/li>\n<\/ul>\n<p>Behavioral characteristics may include stereotypic movements, such as hand-flapping and atypical social development, particularly:<\/p>\n<ul>\n<li style=\"font-weight: 400;\">Shyness<\/li>\n<li style=\"font-weight: 400;\">Limited eye contact<\/li>\n<li style=\"font-weight: 400;\">Memory problems<\/li>\n<li style=\"font-weight: 400;\">Difficulty with face recognition<\/li>\n<\/ul>\n<p>Some individuals with FXS also meet the diagnostic criteria for autism.<\/p>\n<p><strong>If your child suffers with any
