The Main Tests We Use in the Diagnosis of Neurodevelopmental Diseases :

  • Chromosome analysis
  • Chromosomal microarray
  • Exome sequencing
  • Optical mapping
  • Fragile X disease test (detection of FMR1 CGG repeat number)


Hastalığın Tanısının Konulması :

  • Can shape the patient's medication management.
  • It can give information about the prognosis (the course of the disease).
