Microarray analysis in pregnancies with isolated echogenic bowel

To our best knowledge, our study is the first report describing the rate of clinically significant copy number variants in pregnancies with isolated echogenic bowel. According to our results, it seems that pregnancies with isolated echogenic bowel do not have an increased risk for abnormal CMA compared to fetuses with no evidence of sonographic anomalies. Our findings suggest that the consideration to perform CMA analysis in such pregnancies should not differ from any pregnancy with normal ultrasound.
