The China Neonatal Genomes Project

Study Overview
=================
Brief Summary
-----------------
The project will carry out the genetic testing of 100000 neonates in the next 5 years. The aim of the project is to construct the Chinese neonatal genome database, establish the genetic testing standard of neonatal genetic diseases, and promote the industrialization of neonatal genetic disease gene testing, improve the training system for genetic counseling.

Detailed Description
-----------------
There are about 900,000 new cases of birth defects in China every year. There are a large number of hereditary diseases, such as primary immune deficiency diseases, genetic metabolic diseases and multiple malformation syndrome, etc. It is important to identify and diagnose these diseases early in life, which can optimize the treatment strategy, improve the quality of life, and achieve the purpose of accurate treatment. To improve the level of diagnosis and prevention of genetic diseases in children is conducive to the birth and education of newborn in our country. The China Neonatal Genome Project is an important part of the China Human single Target Genome Project. The investigators plan to complete genetic testing of 100,000 newborns within 5 years, establish genetic testing standards for genetic diseases of newborns, and promote precise intervention for birth defects. The Genetic Counseling Branch of China Genetics Society, the Pediatrics Hospital affiliated to Fudan University and hundreds of hospitals in China jointly launched the Chinese newborn Genome Project in Shanghai, China. The project will carry out the genetic testing of 100000 neonates in the next 5 years. The study physician and genetic counselor will provide the consultation to families utilizing all available medical information. In the sequencing analysis of the study, this will include the medical history, physical exam, family history, standard newborn screening report. The aim of the project is to construct the Chinese neonatal genome database, establish the genetic testing standard of neonatal genetic diseases, and promote the industrialization of neonatal genetic disease gene testing, improve the training system for genetic counseling.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Sick Neonatal Cohort, Sequencing<br>Infants and their parents enrolled through Neonatal Intensive Care Unit of member hospitals who are un-randomized to receive genomic sequencing. Results disclosure sessions will include a discussion of: family history report, results from standard newborn screening, any potentially medically relevant findings from the baby's medical history/physical exam, and the results of the genomic sequencing report. | Genetic: Genomic sequencing<br>* Both sick and high-risk newborn un-randomized to receive genomic sequencing will receive a Genomic Newborn Sequencing Report which will include pathogenic or likely pathogenic variants identified in genes associated with childhood-onset disease.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of gene sequencing data in neonatal gene bank | Each newborn that was sequenced was counted as 1. Keep all the data in the gene bank, and finally calculate the number of completed gene sequencing data. | From birth to completion of genetic screening, the process last up to 3 months. | 
| Gene mutation rate | Taking the number of newborn babies as denominator and the number of neonates with gene mutation detected in gene sequencing as molecules, the whole neonatal gene mutation rate in China was obtained. | From birth to completion of genetic screening, the process last up to 3 months. |
