First of all, Trio Whole Exome Sequencing (Trio WES) sequences the ~20,000 protein-coding genes of an affected child alongside both biological parents simultaneously. Essentially, comparing parental genomes filters out harmless inherited variants, immediately uncovering de novo mutations and compound heterozygous disease carriers. As a result, medical geneticists increase diagnostic yield from 25% up to 50% for complex pediatric syndromes.
Book your Trio WES at Henotic Diagnostics for comprehensive genomic clarity. Furthermore, our accredited diagnostic facility operates 24/7 to provide seamless sample collection.
To begin with, Trio WES is the Gold Standard genomic diagnostic evaluation for complex, uncharacterized pediatric genetic conditions. At the same time, experts at Henotic Diagnostics sequence DNA from the affected child and both parents to eliminate false positive variants.
What Does Trio Whole Exome Sequencing Evaluate?
Specifically, Trio WES evaluates single nucleotide variants (SNVs), small insertions/deletions (indels), non-synonymous mutations, and splice-site defects across 20,000 coding genes. Consequently, pediatric neurologists solve diagnostic odysseys for developmental delay, refractory epilepsy, and metabolic disorders. Furthermore, bioinformatic algorithms determine whether variants are new (de novo) or inherited from asymptomatic parents. As a result, physicians provide accurate recurrence risk counseling. In fact, to review clinical research standards, consult the NIH Genetic Testing Registry (GTR) resource.

What is Trio Whole Exome Sequencing?
In general, Trio WES is a simultaneous genomic sequencing strategy. Essentially, exons comprise approximately 1% to 2% of the genome but harbor over 85% of disease-causing mutations. Specifically, Next-Generation Sequencers generate high-depth coverage (100x to 150x) across all coding exons. Therefore, bioinformatic pipelines compare the proband’s DNA against parental samples to instantly identify pathogenic mutations. Additionally, this approach reduces variants of uncertain significance (VUS).
Additionally, high-throughput NGS platforms process trio samples simultaneously to guarantee high sequence depth
What Does Trio Whole Exome Sequencing Check?
Overall, the scan provides complete inheritance filtering and variant classification:
Key Inheritance Patterns & Mutations Identified
✓
De Novo Mutations: First, it detects brand new mutations present in the child but absent in both healthy parents.
✓
Autosomal Recessive Diseases: Second, it uncovers compound heterozygous variants inherited from carrier parents (e.g. SMA, Cystic Fibrosis).
✓
X-Linked Inherited Disorders: In addition, it maps maternal X-chromosome variants passed to affected male offspring.
✓
Inborn Errors of Metabolism: Finally, it identifies rare enzyme gene defects causing metabolic crises.
In addition, bioinformatic software pipelines filter parental variants to pinpoint causative de novo mutations
When Is Trio Whole Exome Sequencing Recommended?
For example, pediatric geneticists and neurologists recommend Trio WES for distinct clinical scenarios. In particular, doctors order trio sequencing for infants presenting with unexplained global developmental delay or intellectual disability. Moreover, it is recommended for children with early-onset epileptic encephalopathy, dysmorphic features, or congenital anomalies. In addition, families with previous affected children use trio WES for reproductive planning.
Moreover, expert genetic counseling translates complex trio NGS findings into definitive medical care plans
Clinical Advantage of Trio Whole Exome Sequencing vs. Singleton Exome Testing
Why Trio WES Provides Higher Diagnostic Rate
Ideally, parents should choose Trio WES over singleton testing if rapid diagnosis is needed for critically ill children. In addition, if a singleton test finds dozens of ambiguous VUS variants, parental sequencing is required anyway. Indeed, starting with Trio WES saves crucial clinical time and expenses.
Trio Whole Exome Sequencing Cost Guide
Genomic Diagnostic Service
Approximate Cost (₹)
Trio Whole Exome Sequencing (Proband + Parents)
First, standard Trio WES pricing is ₹35,000 – ₹45,000.
Rapid Trio WES (STAT NICU/ICU Cases)
Second, Rapid STAT Trio WES costs ₹55,000 – ₹70,000.
Singleton Whole Exome Sequencing (Child Only)
In addition, Singleton WES costs ₹18,000 – ₹25,000.
Pre & Post-Test Genetic Counseling
Finally, expert genetic consultation fee is ₹1,500 – ₹2,500.
Comparison: Trio Whole Exome Sequencing vs. Singleton WES & Karyotype
On one hand, a Singleton WES test analyzes only the child’s DNA without parental context, whereas Trio WES compares parental genomes directly to instantly confirm whether a variant is pathogenic or benign. Consequently, Trio WES achieves superior diagnostic accuracy.
