2.1 Establishment of the NGS panel
Generation of gene-disease association : Monogenic inherited diseases were collected according to the criteria of covering diseases that are severe, actionable, and early onset (refer to the result section), and genes with relatively clear relationship with diseases were determined based on Online Mendelian Inheritance in Man (OMIM) database (https://www.omim.org/).
Age of onset : According to the diseases records in OMIM database, the known minimum onset age of diseases is manually sorted out, which can be divided into 6 categories: <1 year of age (Infants), 1-3 years of age (Toddlers), 3-6 years of age (Preschoolers), 6-12 years of age (Middle Childhood), 12-18 years of age (Young Teens and Teenagers), > 18 years of age (Adulthood).
