Autosomal recessive polycystic kidney disease (ARPKD) is a severe pediatric kidney disorder primarily caused by mutations in the fibrocystin-encoding PKHD1 gene. It is characterized by the progressive development of cysts, eventually leading to renal failure. In order to create patient specific iPSCs, peripheral blood mononuclear cells (PBMCs) from a female patient carrying a homozygous PKHD1 mutation (c.8285A>T(;)(8285A>T)) were reprogrammed using the non-integral Cytotune®-iPS 2.0 Sendai Reprogramming Kit (Invitrogen). Morphology and karyotype of the cells are normal. Pluripotency hallmarks as well as the potential to spontaneously differentiate into all three germ layers were shown by immunofluorescence staining and RT-PCR.

Homologous recombination is a largely error-free DNA repair mechanism conserved across all domains of life and is essential for the maintenance of genome integrity. Not only are the mutations in homologous recombination repair genes probable cancer drivers, some also cause genetic disorders. In particular, mutations in the Bloom (BLM) helicase cause Bloom Syndrome, a rare autosomal recessive disorder characterized by increased sister chromatid exchanges and predisposition to a variety of cancers.

Autosomal recessive proximal renal tubular acidosis (AR-pRTA) with ocular abnormalities is a rare syndrome caused by variants in the SLC4A4 gene, which encodes Na/HCO3 cotransporter (NBCe1). The syndrome primarily affects the kidneys, but also causes extra-renal manifestations. Pancreatic type NBCe1 is located at the basolateral membrane of the pancreatic ductal cells and together with CFTR chloride channel, it is involved in bicarbonate secretion.

Introduction: Musculocontractural Ehlers-Danlos syndrome (mcEDS) is a rare autosomal recessive connective tissue disorder caused by systemic depletion of dermatan sulfate. Symptoms characteristic of mcEDS include multiple contractures, fragile skin with subcutaneous bleeding, and hypermobile joints, which suggest difficulty in perioperative management. However, safe surgical techniques and perioperative management of this disorder remain unknown because of its rarity.

Heterotaxy syndrome is characterized by abnormal left-right arrangement of thoracoabdominal organs and is frequently associated with complex cardiac anomalies. However, cases with predominant extracardiac manifestations are increasingly recognized. This report describes a 20-year-old female of North African descent with consanguineous parentage, who presented with chronic cough and exertional dyspnea persisting over several years.

Bernard-Soulier syndrome (BSS) is a rare autosomal recessive condition that is defined by low platelet count and platelet dysfunction characterized by the absence or dysfunction of the complex on the platelet surface. It is characterized by large defective platelets and thrombocytopenia. BSS is usually presented early in life.
