Understanding FXS

About Fragile X Syndrome

Fragile X Syndrome (FXS) is the most common inherited, single-gene cause of intellectual disability and autism worldwide. It can cause intellectual disabilities, ADHD, autism, speech delay. It can be diagnosed by a DNA blood test and it is estimated that 5% of people with a diagnosis of an Autism Spectrum disorder also have Fragile X Syndrome.

Prevalence

The prevalence of FXS in males is approximately 1 in 3,600 and in females is approximately 1 in 4,000. Further, around 5% of people with Autism Spectrum Disorder also have FXS. It is estimated that in India we have approximately 4 lakh children with FXS, most of whom are undiagnosed and untreated.

Causes

FXS is caused by the expansion of the FMR1 gene on the X chromosome, known as a gene mutation. In some people, known as ‘carriers’ this gene may contain between 50-200 repeats. Fragile X is caused when this gene lengthens to over 200 repeats interfering with the normal production of this protein and therefore normal brain development.

Inheritance

The Fragile X gene may be passed down through each generation. Daughters of male carriers will inherit their fathers affected X chromosome and they will also be carriers. Sonsof male carriers will not inherit their fathers X chromosome and won’t be affected. As females have two X chromosomes, children of female carriers have a 50% chance of inheriting the affected gene.
