Whole Exome Sequencing - Pediatric/Postnatal

Whole Exome Sequencing + SNP Microarray - Pediatric/ Postnatal/ POC

Finding causes of diseases EFFICIENTLY


Whole exome sequencing (WES) is a cost-effective way to identify genetic basis of disorders. Unlike the traditional genetic test that detects one specific gene, WES can test many genes at one time.


Utilizing Different Tools can increases the possibility for diagnostic

For severe intellectual disability as example, the diagnostic rate of the SNP array was 12%. After that, the group of patients in whom no genetic cause was identified were used the WES to test and the diagnostic rate was 27%1.


The testing is ideal for individuals with


Whole exome sequencing (WES)

SNP Microarray


  • A complex/ multiple symptom
  • Unspecified diagnosis/ complex etiology
  • Negative single gene or gene panel sequencing results
  • Disorders with significant genetic heterogeneity
  • Unexplained developmental delay/intellectual disorder (DD/ID)
  • Autistic spectrum disorder (ASD)
  • Multiple congenital anomalies (MCA).


  • Point mutations of single genes

De novo mutations, inherited SNP sites, etc..

  • Insertion-deletion polymorphisms (InDels)
  • Chromosomal Aneuploidies
  • Chromosomal Copy Number Variants (microduplication/microdeletion)
  • Uniparental disomy(UPD)
