It has an autosomal recessive genetic pattern and is characterized by meningo occipital encephalocele, polycystic kidney dysplasia, polydactyly, and hepatobiliary ductal plate malformation. Germline variations in <jats:italic>CEP290<\/jats:italic> have been shown to cause MKS4.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In this study, a 23\u2010year\u2010old Chinese woman who was 18\u2009weeks pregnant was examined. The pregnancy was terminated due to occipital meningocele and enlarged cystic dysplastic kidney revealed by ultrasonography. In addition, the patient had a history of adverse pregnancy whereby the fetus presented with double kidney enlargement. Karyotype analysis and chromosomal microarray examination (CMA) were carried out using amniotic fluid samples. Whole exome sequencing (WES) was performed using tissue specimens of the aborted fetus.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Karyotype and CMA analyses showed normal results. However, compound heterozygous mutations of <jats:italic>CEP290<\/jats:italic> c.3175dup and <jats:italic>CEP290<\/jats:italic> c.1201dup were detected through WES. <jats:italic>CEP290<\/jats:italic> c.1201dup is a novel heterozygous mutation of <jats:italic>CEP290<\/jats:italic> that has not been reported previously.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The findings of this study provide information on the correlation between MKS phenotype and genotype in <jats:italic>CEP290<\/jats:italic>. In addition, these findings indicate that WES is an effective method for detecting genetic causes of multiple structural defects especially those showing normal karyotype and CMA
