A long-running fragile X syndrome screening program in Australia identified 253 individuals. The program informed families about genetic risks, leading to a 26% birth reduction and 61% prenatal diagnosis uptake.

Area of Science:

  • Medical Genetics
  • Public Health Screening

Background:

  • Fragile X syndrome is a significant genetic cause of intellectual disability.
  • Early identification is crucial for genetic counseling and family planning.

Purpose of the Study:

  • To evaluate the effectiveness of a long-term fragile X syndrome screening program in New South Wales.
  • To assess the impact of screening on family awareness, reproductive choices, and genetic service integration.

Main Methods:

  • Screening of 14,225 individuals at intellectual disability facilities.
  • Offered fragile X syndrome testing to 8172 individuals with a 79% uptake.
  • Conducted genetic counseling and offered prenatal diagnosis to at-risk family members.

Main Results:

  • Identified 253 probands with fragile X syndrome.
  • Interviewed and counseled 818 at-risk females.
  • In a subgroup of 90, observed a 26% reduction in births and 61% uptake of prenatal diagnosis.
  • Most participants reported satisfaction and adequate information.

Conclusions:

  • Systematic fragile X syndrome screening is beneficial for identifying affected individuals and families.
  • The program facilitated informed reproductive decision-making and increased prenatal diagnosis uptake.
  • Integration of fragile X screening into community genetic services is recommended.
