Acute interstitial pneumonia
A rare rapidly progressive and histologically distinct form of idiopathic interstitial pneumonia. [from ORDO]
Acute intermittent porphyria
Acute intermittent porphyria (AIP), an autosomal dominant disorder, occurs in heterozygotes for an HMBS pathogenic variant that causes reduced activity of the enzyme porphobilinogen deaminase. AIP is considered "overt" in a heterozygote who was previously or is currently symptomatic; AIP is considered "latent" in a heterozygote who has never had symptoms, and typically has been identified during molecular genetic testing of at-risk family members. Note that GeneReviews does not use the term "carrier" for an individual who is heterozygous for an autosomal dominant pathogenic variant; GeneReviews reserves the term "carrier" for an individual who is heterozygous for an autosomal recessive disorder and thus is not expected to ever develop manifestations of the disorder. Overt AIP is characterized clinically by life-threatening acute neurovisceral attacks of severe abdominal pain without peritoneal signs, often accompanied by nausea, vomiting, tachycardia, and hypertension. Attacks may be complicated by neurologic findings (mental changes, convulsions, and peripheral neuropathy that may progress to respiratory paralysis), and hyponatremia. Acute attacks, which may be provoked by certain drugs, alcoholic beverages, endocrine factors, calorie restriction, stress, and infections, usually resolve within two weeks. Most individuals with AIP have one or a few attacks; about 3%-8% (mainly women) have recurrent attacks (defined as >3 attacks/year) that may persist for years. Other long-term complications are chronic renal failure, hepatocellular carcinoma (HCC), and hypertension. Attacks, which are very rare before puberty, are more common in women than men. Latent AIP. While all individuals heterozygous for an HMBS pathogenic variant that predisposes to AIP are at risk of developing overt AIP, most have latent AIP and never have symptoms. [from GeneReviews]
Acromegaly
A rare acquired endocrine disease related to excessive production of growth hormone (GH) and characterized by progressive somatic disfigurement (mainly involving the face and extremities) and systemic manifestations. [from ORDO]
Somatotroph adenoma
AIP familial isolated pituitary adenoma (AIP-FIPA) is defined as the presence of an AIP germline pathogenic variant in an individual with a pituitary adenoma (regardless of family history). The most commonly occurring pituitary adenomas in this disorder are growth hormone-secreting adenomas (somatotropinoma), followed by prolactin-secreting adenomas (prolactinoma), growth hormone and prolactin co-secreting adenomas (somatomammotropinoma), and nonfunctioning pituitary adenomas (NFPA). Rarely TSH-secreting adenomas (thyrotropinomas) are observed. Clinical findings result from excess hormone secretion, lack of hormone secretion, and/or mass effects (e.g., headaches, visual field loss). Within the same family, pituitary adenomas can be of the same or different type. Age of onset in AIP-FIPA is usually in the second or third decade. [from GeneReviews]
Autoimmune pancreatitis
A rare pancreatic disease characterized by chronic non-alcoholic pancreatitis that presents with abdominal pain, steatorrhea, obstructive jaundice and responds well to steroid therapy and is seen in two subforms: type which affects elderly males, involves other organs and has increased immunoglobin G4 (IgG4) levels and type 2 which affects both sexes equally but presents at a younger age and has no other organ involvement or increased IgG4 levels. [from ORDO]
Hypophysitis
An inflammatory process in the pituitary gland. [from NCI]
Family history
Information about close relatives of an individual who is the proband of a study or who is being investigated with the goal of identifying a medical diagnosis. Usually, the family history includes information from three generations of relatives, including children, brothers and sisters, parents, aunts and uncles, nieces and nephews, grandparents, and cousins. [from HPO]
Adenoma
A neoplasm arising from the epithelium. It may be encapsulated or non-encapsulated but non-invasive. The neoplastic epithelial cells may or may not display cellular atypia or dysplasia. In the gastrointestinal tract, when dysplasia becomes severe it is sometimes called carcinoma in situ. Representative examples are pituitary gland adenoma, follicular adenoma of the thyroid gland, and adenomas (or adenomatous polyps) of the gastrointestinal tract. [from NCI]
Microcystic adenoma
A benign epithelial neoplasm characterized by a microcystic pattern. The cystic spaces are lined by small cuboidal cells without evidence of significant cytologic atypia. [from NCI]
Papillary adenoma
An adenoma characterized by the presence of papillary epithelial patterns. [from NCI]
Pituitary gland disorder
A non-neoplastic or neoplastic disorder that affects the pituitary gland. [from NCI]
Hyperpituitarism
Hypersecretion of one or more pituitary hormones. This can occur in conditions in which deficiency in the target organ leads to decreased hormonal feedback, or as a primary condition most usually in connection with a pituitary adenoma. [from HPO]
Hypothalamic disorder
Neoplastic, inflammatory, infectious, and other diseases of the hypothalamus. Clinical manifestations include appetite disorders; autonomic nervous system diseases; sleep disorders; behavioral symptoms related to dysfunction of the limbic system; and neuroendocrine disorders. [from MONDO]
Familial isolated pituitary adenoma
A rare, hereditary endocrine tumor characterized by a benign pituitary adenoma that is either secreting (e.g. prolactin, growth hormone, thyroid stimulating hormone) or non-secreting. Symptoms may occur due to either the hormonal hypersecretion and/or the mass effect of the lesion on local structures in the brain. [from ORDO]
Pituitary adenoma, growth hormone-secreting, 2
Any pituitary gland adenoma in which the cause of the disease is a mutation in the GPR101 gene. [from MONDO]
Growth hormone-producing pituitary gland carcinoma
Growth hormone-producing pituitary neuroendocrine tumor that has spread from its original site of growth to another anatomic site. [from NCI]
