A rare genetic disease characterized by early-onset severe obesity due to mutations in single genes acting on the development and function of the hypothalamus or the leptin-melanocortin pathway, leading to disruption of energy homeostasis and endocrine dysfunction. Patients present with a body mass index over three standard deviations above normal at less than five years of age, accompanied by a variety of signs and symptoms according to the mutated gene, including hyperphagia, insulin resistance, reduced basal metabolic rate, or hypogonadism, among others. |

German syndrome is an autosomal recessive arthrogryposis syndrome, described in 5 cases. Three of the four known families with affected children were Ashkenazi Jews. German syndrome is characterized by arthrogryposis, hypotonia-hypokinesia sequence, and lymphedema. Patients present distinct craniofacial appearance (tall forehead and carp-shaped mouth, cleft palate), contractures, severe hypotonia manifesting as motor delay, and swallowing difficulties. The disease has a severe morbidity and mortality rate and survivors present a small stature, hypotonia, frequent upper respiratory infections, and psychomotor delay. There have been no further descriptions in the literature since 1987. |

A rare genetic hemolytic uremic syndrome (HUS) characterized by infantile onset of relapsing episodes of microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury. The episodes are often preceded by viral infections. Affected individuals typically present persistent hypertension, hematuria, and proteinuria (sometimes in the nephrotic range) and develop chronic kidney disease with age. |

Chapare hemorrhagic fever, caused by the Chapare virus (a new arenavirus), discovered from a small outbreak in Cochabamba, Bolivia between 2003 and 2004, is an acute viral hemorrhagic fever characterized by fever, myalgia, arthralgia, and multiple hemorrhagic signs. About a third of untreated cases go on to develop more severe symptoms with delirium, coma and convulsions and death (in one case). No other cases have been reported since. |

Hepatic fibrosis-renal cysts-intellectual disability syndrome is a rare, syndromic intellectual disability characterized by early developmental delay with failure to thrive, intellectual disability, congenital hepatic fibrosis, renal cystic dysplasia, and dysmorphic facial features (bilateral ptosis, anteverted nostrils, high arched palate, and micrognathia). Variable additional features have been reported, including cerebellar anomalies, postaxial polydactyly, syndactyly, genital anomalies, tachypnea. There have been no further descriptions in the literature since 1987. |

A rare hepatic disease characterized by graft infection with the hepatitis B virus (HBV) after liver transplantation, due to persistence and reactivation of HBV in extrahepatic sites (also despite previous clearance of the HBs antigen from serum, as shown by laboratory examination), followed by re-invasion of the graft. It may develop between two weeks and several years post transplantation. Clinico-pathological features are variable and range from mild self-limited hepatitis, chronic active hepatitis, and fulminant hepatitis, to fibrosing cholestatic hepatitis. The condition is associated with significantly reduced graft survival rates and overall patient survival. |

A rare hereditary angioedema characterized by potentially life-threatening episodes of subcutaneous and/or submucosal edema without urticaria, associated with C1 esterase inhibitor (C1-INH) deficiency. Hereditary angioedema (HAE) type 1 is caused by quantitative, HAE type 2 by qualitative defects of C1-INH. The two subtypes are clinically indistinguishable. Patients may present at any age (but most commonly in childhood) with recurrent attacks of nonpitting edema of the skin, severe abdominal symptoms such as pain and swelling, and/or respiratory distress due to upper respiratory airways involvement. Genital, bladder, muscle, or joint swelling may occur in some cases. |

Hereditary arterial and articular multiple calcification syndrome is a very rare genetic vascular disease of autosomal recessive inheritance, described in less than 20 patients to date, characterized by adult-onset (as early as the second decade of life) isolated calcification of the arteries of the lower extremities (including the iliac, femoral, and tibial arteries) as well as the capsule joints of the fingers, wrists, ankles and feet, and that usually manifests with mild paresthesias of the lower extremities, intense joint pain and swelling, and early onset arthritis of affected joints. |

A genetic condition characterized by hereditary susceptibility to breast and/or ovarian cancer. It can be defined using family history criteria, or through identification of germline pathogenic variants (GPVs) in clinically validated HBOC genes. However, the genetic basis of about half of clinical HBOC is currently unknown or unexplained by single-gene variants, and approximately half of individuals who harbor PVs in HBOC genes do not have a suggestive family history. |

A metabolic disorder characterized by prolonged apnea after the use of certain anesthetic drugs, including the muscle relaxants succinylcholine or mivacurium and other ester local anesthetics. The duration of the prolonged apnea varies significantly depending on the extent of the enzyme deficiency. It is caused by mutations in the BCHE located on chromosome 3 (3q26.1-3q26.2) and multiple atypical variants have been identified. The condition is transmitted as an autosomal recessive trait. |
