The aim of the study was to assess the features of development of renal and extrarenal cysts, arterial hypertension, syndrome of portal hypertension in autosomal recessive polycystic kidney disease (ARPKD) in children. Patients and me­thods. With the aim of establishing the type of inheritance of polycystic kidney disease the genealogical analysis of 12 families, clinical ultrasound of the kidneys and abdominal organs, computed tomography. The study included 14 children with ARPKD. Conducted follow-up study of 14 children with ARPKD to determine the age by the detection of cysts based on ultrasound, the features of the initial clinical manifestations and course, complications and outcome.Results: the Age of the children back to the time of detection of the cysts in the kidneys based on ultrasound when ARPKD was 2.3 ± 0.4 month. Identified a high incidence of arterial hypertension in neonates and infants with ARPKD at 92.9%. Extrarenal location of the cysts is set at 71.4%. Syndrome of portal hypertension, bleeding from varicose veins of esophagus and stomach, melanau installed in 5 (35,7%) children. Of the 14 in 5 (35,7%) patients diagnosed ARPKD children with liver fibrosis, which has a favorable prognosis without the formation of renal failure in infants and early childhood, 9 (64,3%) diagnosed with classic ARPKD in neonates and infants that is characterized by progression to end-stage renal disease in the first year of life.

Autosomal recessive polycystic kidney disease (ARPKD) is a rare disorder and one of the most severe forms of polycystic kidney disease, leading to end-stage renal disease (ESRD) in childhood. PKHD1 is the gene that is responsible for the vast majority of ARPKD. However, some cases have been related to a new gene that was recently identified (DZIP1L gene), as well as several ciliary genes that can mimic a ARPKD-like phenotypic spectrum. In addition, a number of molecular pathways involved in the ARPKD pathogenesis and progression were elucidated using cellular and animal models. However, the function of the ARPKD proteins and the molecular mechanism of the disease currently remain incompletely understood. Here, we review the clinics, treatment, genetics, and molecular basis of ARPKD, highlighting the most recent findings in the field.

Abstract Background Autosomal recessive polycystic kidney disease (ARPKD) is caused by mutations in the PKHD1 gene. The clinical spectrum is often more variable than previously considered. We aimed to analyze the clinical features of genetically diagnosed ARPKD in the Japanese population. Methods We conducted a genetic analysis of patients with clinically diagnosed or suspected ARPKD in Japan. Moreover, we performed a minigene assay to elucidate the mechanisms that could affect phenotypes. Results PKHD1 pathogenic variants were identified in 32 patients (0–46 years). Approximately one-third of the patients showed prenatal anomalies, and five patients died within one year after birth. Other manifestations were detected as follows: chronic kidney disease stages 1–2 in 15/26 (57.7%), Caroli disease in 9/32 (28.1%), hepatic fibrosis in 7/32 (21.9%), systemic hypertension in 13/27 (48.1%), and congenital hypothyroidism in 3 patients. There have been reported that truncating mutations in both alleles led to severe phenotypes with perinatal demise. However, one patient without a missense mutation survived the neonatal period. In the minigene assay, c.2713C > T (p.Gln905Ter) and c.6808 + 1G > A expressed a transcript that skipped exon 25 (123 bp) and exon 41 (126 bp), resulting in an in-frame mutation, which might have contributed to the milder phenotype. Missense mutations in cases of neonatal demise did not show splicing abnormalities. Conclusion Clinical manifestations ranged from cases of neonatal demise to those diagnosed in adulthood. The minigene assay results indicate the importance of functional analysis, and call into question the fundamental belief that at least one non-truncating mutation is necessary for perinatal survival.
