Abstract excerpt

OBJECTIVE: To examine the concordance rate of non-chromosomal congenital malformations in twin pairs based on zygosity. DESIGN: Retrospective cohort study. SETTING: A tertiary hospital in Korea. POPULATION: Twin pairs born at Seoul National University Hospital between 2001 and 2019. METHODS: Congenital malformations were diagnosed by postnatal workups of neonates or autopsy in cases of stillborn infants. Zygosity...
