Label	Id	Description
Mitral Valve Prolapse	D008945	[Abnormal protrusion or billowing of one or both of the leaflets of MITRAL VALVE into the LEFT ATRIUM during SYSTOLE. This allows the backflow of blood into left atrium leading to MITRAL VALVE INSUFFICIENCY; SYSTOLIC MURMURS; or CARDIAC ARRHYTHMIA.]
ConceptScheme	ConceptScheme	[A set of concepts, optionally including statements about semantic relationships between those concepts.]
Mitral Valve Insufficiency	D008944	[Backflow of blood from the LEFT VENTRICLE into the LEFT ATRIUM due to imperfect closure of the MITRAL VALVE. This can lead to mitral valve regurgitation.]
Adenoma, Pleomorphic	D008949	[A benign, slow-growing tumor, most commonly of the salivary gland, occurring as a small, painless, firm nodule, usually of the parotid gland, but also found in any major or accessory salivary gland anywhere in the oral cavity. It is most often seen in women in the fifth decade. Histologically, the tumor presents a variety of cells: cuboidal, columnar, and squamous cells, showing all forms of epithelial growth. (Dorland, 27th ed)]
Hallux Varus	D050488	[Displacement of the great toe (HALLUX) towards the midline or away from the other TOES. It can be congenital or acquired., Angulation of the first metatarsal bone towards the midline. This is associated with angulation of the phalanges of the same toe away from the midline (HALLUX VALGUS).]
Kaposi Varicelliform Eruption	D007617	[A disseminated vesicular-pustular eruption caused by the herpes simplex virus (HERPESVIRUS HOMINIS), the VACCINIA VIRUS, or Varicella zoster (HERPESVIRUS 3, HUMAN). It is usually superimposed on a preexisting, inactive or active, atopic dermatitis (DERMATITIS, ATOPIC).]
Bunion, Tailor's	D050489	[Abnormal swelling of the outer aspect of the fifth metatarsal head affecting the fifth METATARSOPHALANGEAL JOINT.]
Bunion	D000071378	[Abnormal swelling of the inner aspect of the first metatarsal head affecting the first METATARSOPHALANGEAL JOINT.]
Mixed Connective Tissue Disease	D008947	[A syndrome with overlapping clinical features of systemic lupus erythematosus, scleroderma, polymyositis, and Raynaud's phenomenon. The disease is differentially characterized by high serum titers of antibodies to ribonuclease-sensitive extractable (saline soluble) nuclear antigen and a "speckled" epidermal nuclear staining pattern on direct immunofluorescence.]
Mitral Valve Stenosis	D008946	[Narrowing of the passage through the MITRAL VALVE due to FIBROSIS, and CALCINOSIS in the leaflets and chordal areas. This elevates the left atrial pressure which, in turn, raises pulmonary venous and capillary pressure leading to bouts of DYSPNEA and TACHYCARDIA during physical exertion. RHEUMATIC FEVER is its primary cause.]
Kartagener Syndrome	D007619	[An autosomal recessive disorder characterized by a triad of DEXTROCARDIA; INFERTILITY; and SINUSITIS. The syndrome is caused by mutations of DYNEIN genes encoding motility proteins which are components of sperm tails, and CILIA in the respiratory and the reproductive tracts.]
Bronchiectasis	D001987	[Persistent abnormal dilatation of the bronchi.]
Dextrocardia	D003914	[A congenital defect in which the heart is located on the right side of the THORAX instead of on the left side (levocardia, the normal position). When dextrocardia is accompanied with inverted HEART ATRIA, a right-sided STOMACH, and a left-sided LIVER, the combination is called dextrocardia with SITUS INVERSUS. Dextrocardia may adversely affect other thoracic organs.]
Adenoma, Acidophil	D000239	[A benign tumor, usually found in the anterior lobe of the pituitary gland, whose cells stain with acid dyes. Such pituitary tumors may give rise to excessive secretion of growth hormone, resulting in gigantism or acromegaly. A specific type of acidophil adenoma may give rise to nonpuerperal galactorrhea. (Dorland, 27th ed)]
Adenoma, Chromophobe	D000238	[A benign tumor of the anterior pituitary in which the cells do not stain with acidic or basic dyes.]
Adenoma, Basophil	D000237	[A small tumor of the anterior lobe of the pituitary gland whose cells stain with basic dyes. It may give rise to excessive secretion of ACTH, resulting in CUSHING SYNDROME. (Dorland, 27th ed)]
Adenolymphoma	D000235	[A benign tumor characterized histologically by tall columnar epithelium within a lymphoid tissue stroma. It is usually found in the salivary glands, especially the parotid.]
Blepharophimosis	D016569	[The abnormal narrowness of the palpebral fissure in the horizontal direction caused by the lateral displacement of the medial canthi of the eyelids. (Dorland, 27th ed)]
Neoplasms, Fibroepithelial	D018225	[Neoplasms composed of fibrous and epithelial tissue. The concept does not refer to neoplasms located in fibrous tissue or epithelium.]
Kearns-Sayre Syndrome	D007625	[A mitochondrial disorder featuring the triad of chronic progressive EXTERNAL OPHTHALMOPLEGIA, cardiomyopathy (CARDIOMYOPATHIES) with conduction block (HEART BLOCK), and RETINITIS PIGMENTOSA. Disease onset is in the first or second decade. Elevated CSF protein, sensorineural deafness, seizures, and pyramidal signs may also be present. Ragged-red fibers are found on muscle biopsy. (Adams et al., Principles of Neurology, 6th ed, p984)]
