The molecular genetic diagnosis confirmed the pre-ES clinical diagnosis, with detection of pathogenic variants in cystic kidney disease or nephronophthisis genes, including PKD1 (25), PKD2 (3), PKHD1 (25), NPHP3 (1), WDR19 (1), RPGRIP1L (1), BBS1 (1), BBS2 (1), and SDCCAG8 (1). This evidence concerns the gene PKD1 and cystic kidney disease.
