Abstract

Paracentric inversion of chromosome 12 is a rare chromosomal aberration, which has familial inheritance in a few cases. We encountered a 2-year-old girl who presented developmental delay, failure to thrive, patent ductus arteriosus, choanal atresia, laryngomalacia, and mild facial dysmorphism. Chromosome studies from peripheral blood showed a 46, XX, inv(12)(q13q22) karyotype. The inversion was also found in her mother. The authors report the first case of paracentric inversion of chromosome 12 in Korea with a review of literature.
