What is ExomePlus Trio?

ExomePlus Trio analysis enables the simultaneous examination of approximately 20,000 genes to detect genetic changes such as Single Nucleotide Variants (SNVs), Insertions or Deletions (Indels), and Copy Number Variations (CNVs) at a >1 exon level. The approach involves sequencing a family trio (typically the patient and both biological parents). By correlating variants with familial inheritance patterns can significantly improve our ability to identify the genetic cause of a disease. It enhances the accuracy of variant calling and enables comprehensive analysis across all modes of inheritance, including autosomal recessive, autosomal dominant, and X-linked. The analysis is also capable of identifying de novo mutations and ruling out chromosomal abnormalities.

What is the significance of this test?

  • Enhanced diagnostic accuracy: Trio analysis significantly increases the accuracy of identifying disease-causing mutations compared to analysing the exome of only the affected individual; it can help filter out benign variants and identify the specific mutations responsible for a condition
  • Identification of de novo mutations: It can identify new mutations that occur in the child’s genome and are not present in either of the parents
  • Clarification of inheritance patterns: It can clarify inheritance patterns, helping to determine whether a condition is inherited in a recessive, dominant, or X-linked manner
  • Improved genetic counseling: It provides valuable information for genetic counseling, helping families understand the risk of disease recurrence in future pregnancies
  • Diagnosis of undiagnosed conditions: It is particularly useful for diagnosing complex or undiagnosed genetic conditions, especially in children with developmental delays, intellectual disabilities, or congenital anomalies;it is also useful in prenatal diagnosis, where it enables efficient detection of inherited genetic variants
  • Efficient variant filtering: By obtaining genomic data on the affected child and his/her parents, variants that are found in the unaffected parents can be easily removed from the variant list of the affected child leaving a much smaller list of potentially pathogenic variants
