FRG1B


Fragile X Syndrome (frg1b)

Description

Fragile X syndrome (frg1b) is a genetic disorder that affects the X chromosome. It is the most common inherited cause of intellectual disability and the second most common cause of autism spectrum disorder (ASD).

frg1b is caused by a mutation in the FMR1 gene, which is located on the X chromosome. This gene produces a protein called FMRP, which is essential for normal brain development. In people with frg1b, the FMR1 gene is either mutated or deleted, leading to a deficiency of FMRP.

Associated Diseases

frg1b can cause a range of symptoms, which can vary in severity. Some of the most common symptoms include:

  • Intellectual disability
  • Autism spectrum disorder
  • Language delays
  • Social difficulties
  • Hyperactivity
  • Attention deficit disorder
  • Anxiety
  • Seizures

frg1b can also be associated with physical features, such as:

  • Large head
  • Long, narrow face
  • Prominent forehead
  • Large ears
  • Long fingers
  • Hyperextensible joints

Did you Know ?

Approximately 1 in 4,000 males and 1 in 8,000 females have frg1b. This means that frg1b is more common in males than in females.
