Huntington's disease Huntington's disease (HD), also known as Huntington's chorea, is an inherited disorder that results in death of brain cells.[4] The earliest symptoms are often subtle problems with mood or mental abilities.[1] A general lack of coordination and an unsteady gait often follow.[2] As the disease advances, uncoordinated, jerky body movements become more apparent.[1] Physical abilities gradually worsen until coordinated movement becomes difficult and the person is unable to talk.[1][2] Mental abilities generally decline into dementia.[3] The specific symptoms vary somewhat between people.[1] Symptoms usually begin between 30 and 50 years of age, but can start at any age.[4][3] The disease may develop earlier in life in each successive generation.[1] About eight percent of cases start before the age of 20 years and typically present with symptoms more similar to Parkinson's disease.[3] People with HD often underestimate the degree of their problems.[1]
Hoyeraal-Hreidarsson syndrome Hoyeraal-Hreidarsson syndrome (HHS) is a very rare multisystem X-linked recessive disorder characterized by excessively short telomeres and is considered a severe form of dyskeratosis congenita.[1][2] Being an X-linked disorder, HHS primarily affects males. Patients with HHS typically present in early childhood with cerebellar hypoplasia, immunodeficiency, progressive bone marrow failure, and intrauterine growth retardation.[1] The primary cause of death in HHS is bone marrow failure, but mortality from cancer and pulmonary fibrosis is also significant.[3][4]
