Chulalongkorn University Launches Groundbreaking Newborn Genome Project

The Center of Excellence in Medical Genetics at Chulalongkorn University in Bangkok has initiated a pioneering project aimed at enhancing early detection and prevention of genetic diseases in newborns. Launched on October 17, 2025, the project utilizes advanced Long-Read Whole Genome Sequencing technology to screen for 113 genetic diseases. This innovative approach is expected to significantly improve health outcomes by enabling early intervention.

Transforming Healthcare Through Genomic Insights

Modern medicine is undergoing a transformation through the application of genomic medicine, a field that decodes the genetic underpinnings of diseases. This project allows healthcare providers to identify individual predispositions to various illnesses, predict the age at which symptoms may emerge, and determine the most effective medications for each patient. According to Professor Dr. Vorasuk Shotelersuk, the Director of the Center of Excellence in Medical Genetics, “Why wait until a person is sick to check their genetic information? We can screen newborns and prevent symptoms before they appear.”

The project emphasizes the importance of early genetic knowledge, as the genetic information remains constant throughout a person’s life. By identifying potential health risks at birth, healthcare professionals can implement preventive measures and treatment strategies tailored to each child’s needs.

Utilizing Advanced Sequencing Technology

The initiative employs Long-Read Whole Genome Sequencing, a sophisticated DNA sequencing method that allows for comprehensive analysis of a child’s genetic makeup. This technology enables the detection of complex mutations that may not be identified through traditional sequencing methods. The project has received approval from the Human Research Ethics Committee at Chulalongkorn University and is currently recruiting pregnant women to participate, aiming for approximately 300 participants in its first year.

Upon delivery at Chulalongkorn Hospital, blood samples will be collected from the umbilical cord, ensuring a painless process for both mother and child. The extracted DNA will then be sequenced to identify mutations linked to severe, treatable conditions that may manifest during the early years of life.

“We will analyze 246 genes associated with 113 treatable childhood diseases, with results communicated to parents within 60 days,” Professor Dr. Vorasuk stated. By focusing on conditions that typically present within the first five years, the project aims to provide timely interventions that can significantly impact a child’s health trajectory.

Shifting Towards Personalized Medicine

Historically, medical treatments have been based on population averages, often leaving a subset of patients without effective solutions. “Genetic sequencing changes this,” noted Professor Dr. Vorasuk. He explained that personalized medicine enables healthcare providers to move from a one-size-fits-all approach to more individualized care, predicting responses to medications and potential side effects based on genetic profiles.

The evolution of DNA sequencing technology has been remarkable since the 1970s, progressing from reading single base pairs to the comprehensive analyses provided by Long-Read Whole Genome Sequencing. This advancement allows for better detection of genetic disorders and more informed healthcare decisions.

Examples of conditions that can be detected through this screening include:

• Blood disorders, such as thalassemia
• Neuromuscular diseases, including muscular dystrophy
• Immune deficiencies, like combined immunodeficiency
• Hearing loss disorders, such as congenital auditory nerve deafness
• Metabolic conditions, including phenylketonuria

By identifying these conditions early, healthcare providers can initiate treatment before severe symptoms arise. For instance, a child with a genetic mutation leading to retinoblastoma may require treatment to preserve their eyesight, which is more effective when detected early.

Looking ahead, Professor Dr. Vorasuk envisions genomic knowledge becoming integral to future healthcare practices. “Who would live a better life—someone who knows their genome from birth, or someone who does not?” he posed, underscoring the potential for enhanced preventative care and targeted treatment strategies.

As genetic technology evolves and costs decrease, Chulalongkorn University’s project could serve as a model for similar initiatives across Thailand and beyond, ultimately granting all children access to their genetic information from birth.
