China Embryo Genome Project Launched with Plan to Sequence 100,000 Newborn Genomes in Five Years

On August 7, 2016, the “China Neonatal Genomics Project” and the “China Embryo Genomics Project” were officially launched, constituting an important component of China’s “Human Single-Target Genomics Project.”

The official launch of the China Newborn Genomics Project aims to build a genomic database for Chinese newborns, establish standards for genetic testing of neonatal hereditary diseases, fundamentally reduce birth defects, and safeguard public health. The initiation of this project is expected to accelerate the development of China’s gene sequencing industry.

It is reported that the China Newborn Genomics Project will conduct genomic testing on 100,000 newborn samples over the next five years. The initiative aims to build a Chinese newborn genomic database, establish standards for genetic testing of neonatal hereditary diseases, promote the industrialization of such testing, formulate guidelines for genetic counseling on neonatal hereditary conditions, collaborate with hospitals to provide genetic counseling training, and improve the overall genetic counseling training system.

Huang Guoying, President of the Children’s Hospital of Fudan University, stated that there are numerous genetic disorders in clinical practice, such as primary immunodeficiency diseases, inherited metabolic disorders, and multiple congenital anomaly syndromes. Early detection and definitive diagnosis of these conditions are of great significance, as they enable optimization of treatment strategies, improvement of quality of life, and achievement of precision medicine goals. For instance, timely metabolic screening and genetic diagnosis for children with phenylketonuria (PKU) allow for the development of personalized intervention strategies, including dietary management and pharmacological therapy. With such interventions, affected children can grow and develop normally; however, missing the critical window for treatment may result in irreversible damage to the nervous system and other organs.

On the same day, to further unravel the mysteries of embryonic development, promote the clinical application of new technologies in diagnostic practices, and improve the diagnostic accuracy for embryos in clinical settings, the Genetic Counseling Branch of the Chinese Society of Genetics, in collaboration with the Center for Reproductive Medicine of Shandong University, launched the China Embryo Genome Project. The project aims to construct a Chinese embryo genome database, establish a genetic counseling system and standardized report interpretation guidelines for preimplantation genetic testing, and develop a training framework for genetic counseling in preimplantation genetic testing.

Genes are functional segments of DNA molecules, serving as the basic units of genetic information and the fundamental determinants of all biological species. Genes dictate human life cycles—from birth to aging, illness, and death—and underpin health, vitality, and longevity, acting as the master regulators of life. Wherever there is life, there are genes; the existence and decline of all living organisms are governed by genes. Traits such as physical appearance, height, weight, skin color, and personality are inextricably linked to one’s genetic makeup.

Modern medical research has demonstrated that, with the exception of trauma, nearly all diseases are associated with genes. Just as blood is classified into different blood types, normal human genes are categorized into distinct genotypes, known as genetic polymorphisms. Different genotypes exhibit varying sensitivities to environmental factors; susceptible genotypes can lead to disease under the influence of such factors. Furthermore, diseases directly caused solely by abnormal genes are referred to as genetic disorders.

Genetic Testing Flowchart

Genetic testing is a technology that analyzes DNA from blood, other bodily fluids, or cells. The primary methods include quantitative fluorescent PCR, gene chips, liquid biochips, and microfluidics.

The significance of genetic testing is threefold:

First, determine whether you carry familial pathogenic genes;

Second, to assist individuals in making appropriate medication choices, thereby avoiding adverse drug reactions and medication waste;

Third, genetic testing provides the best basis for health risk management.

Comparison Chart: Routine Testing vs. Genetic Testing

According to the "Report on Birth Defects Prevention and Control in China" released by the former Ministry of Health in 2012, the incidence rate of birth defects in China was 5.6%, with approximately 900,000 new cases annually. The "China Cancer Report" published by the World Health Organization in 2014 indicated that the global cancer incidence rate increased by 11% over the previous four years, with China recording the highest number of new cases.

Professor He Lin, an academician of the Chinese Academy of Sciences and a member of the Genetic Counseling Branch of the Chinese Society of Genetics, stated that there are currently as many as 7,000 known genetic diseases in humans. In China, approximately 900,000 newborns are born with birth defects each year. With certain social factors remaining persistently high, “we must start from pediatrics and from the embryonic stage to fundamentally reduce birth defects, safeguard the health of the entire population, and truly realize the Healthy China initiative.”

It is reported that the launch of the Neonatal Genomics Program will help further advance China’s gene sequencing industry, with related listed companies poised to seize new development opportunities.
