AbstractProgressive familial intrahepatic cholestasis (PFIC) is a heterogeneous group of autosomal recessive disorders of childhood which presents with intermittent or progressive episodes of cholestasis, with jaundice and pruritus as most common presenting symptoms. PFIC type 3 occurs due to mutations in the ABCB4 gene, mutation in this gene has wide spectrum of features which include intrahepatic stones, cholelithiasis, PFIC type 3, and intrahepatic cholestasis of pregnancy. Here, we are reporting a peculiar case of young male adolescent with novel variant compound heterozygote missense mutation in ABCB4 gene who had gall stone as initial symptom, followed by symptoms of PFIC and eventually decompensated chronic liver disease.

Leptin and its receptor are essential for regulating food intake, energy expenditure, glucose homeostasis and fertility. Mutations within leptin or the leptin receptor cause early-onset obesity and hyperphagia, as described in human and animal models. The effect of both heterozygous and homozygous variants is much more investigated than compound heterozygous ones. Recently, we discovered a spontaneous compound heterozygous mutation within the leptin receptor, resulting in a considerably more obese phenotype than described for the homozygous leptin receptor deficient mice. Accordingly, we focus on compound heterozygous mutations of the leptin receptor and their effects on health, as well as possible therapy options in human and animal models in this review.

Objective of the Paper: to describe a clinical case of paediatric hypophosphatasia (HPP) and identify clinical signs, most characteristic of the paediatric HPP form. Key Points. HPP is an congenital rickets-like disease caused by reduced activity of tissue-nonspecific alkaline phosphatase (ALP). According to the time of manifestation, there are perinatal, infant, paediatric, and adult HPPs. The article describes a clinical case of paediatric HPP in a 3.5-year old boy. HPP was diagnosed due to reduced ALP and characteristic X-ray findings. The diagnosis was confirmed with DNA testing: compound heterozygous mutation in с.571 G>A/с.144_148dup of ALPL was found. Conclusion. Typical findings in paediatric HPP are growth retardation and muscular hypotonia, motor retardation; gait disturbances, myalgia, marked fatigue causing limited period of walking; rachitic deformations, premature loss of milk teeth with unchanged roots, respiratory disturbances, and frequent bronchopulmonary disorders. Keywords: hypophosphatasia, children, alkaline phosphatase.
