STUDY QUESTION: What is the frequency of major chromosome abnormalities in a population-based diagnostic data set of genomic tests performed on miscarriage, fetal and infant samples in a state with >73 000 annual births? SUMMARY ANSWER: The overall frequency of major chromosome abnormalities in the entire cohort was 28.2% (2493/8826), with a significant decrease in the detection of major chromosome abnormalities with later developmental stage, from 50.9% to 21.3% to 15.6% of tests in the miscarriage, prenatal and postnatal cohorts, respectively. WHAT IS KNOWN ALREADY: Over the past decade, technological advances have revolutionized genomic testing at every stage of reproduction. Chromosomal ..View full abstract
