Prenatal diagnosis of de novo isochromosome 4p with an unbalanced t(4;9) translocation in a fetus with congenital anomalies: A case report and literature review

Prenatal diagnosis of de novo isochromosome 4p with an unbalanced t(4;9) translocation in a fetus with congenital anomalies: A case report and literature review

Objective: We present the first case of prenatally diagnosed isochromosome 4p with whole 4q arm translocating to chromosome 9p23 and review the literature. Case Report: A 26-year-old woman underwent amniocentesis at 25 weeks of gestation because of an abnormal ultrasound examination. Routine chromos...
