Two expectant mothers underwent amniocentesis for cytogenetic analysis and chromosomal microarray evaluation (CMA) following abnormal ultrasound conclusions. Case 1 presented short nasal bone and instance 2 showed absent nasal bone tissue, ventricular septal problem and umbilical cord circling in ultrasonic examination. G-banding evaluation showed that the two fetuses presented regular karyotypic outcomes while CMA detected 1.796 Mb (case 1) and 1.242 Mb (instance 2) microduplications in the order of 1q21.1q21.2 individually. Moreover, the CMA also revealed a 1.2 Mb microdeletion of 8p23.3 in the event 1. The few in case 1 decided to terminate the pregnancy, although the few just in case 2 continued the maternity last but not least delivered a male infant who provided low nasal bridge and ventricular septal problem. The 1q21.1q21.2 duplications inside our report had been located in the distal 1q21.1 area, overlapping with 1q21.1 duplication syndrome. Instance 2 ended up being the first reported live birth with 1q21.1 duplication relating to prenatal CMA recognition in Asia. The genotype-phenotype of 1q21.1 duplication is difficult because of the phenotypic variety, incomplete penetrance, and not enough obvious characteristics. So it's hard to predict the postnatal development and illnesses clinically. Therefore, long term follow up is necessary for newborn babies with 1q21.1 duplication, regardless of whether the duplication is de novo or passed down.The genotype-phenotype of 1q21.1 duplication is complicated because of the phenotypic diversity, partial penetrance, and not enough apparent characteristics.
