Prenatal diagnosis of fetal multicystic dysplastic kidney via high-resolution whole-genome array

Conclusions In the present study, the frequency of chromosomal abnormalities in MCDK fetuses was 4.17% and all rearrangements were imbalanced aberrations. CMA was able to increase the pathogenic detection rate to 16.7% in MCDK fetuses with normal karyotype. Critical regions for RCAD syndrome, WBS and copy number variants of 22q11.1 duplication, 4q35.2 deletion, 22q13.33 duplication and 1p33 duplication were associated with fetal MCDK. Genes PEX26, ELN, HNF1B, ALG12, FRG1, FRG2 and CYP4A11 were possible candidates for fetal MCDK.
