Nephroblastoma

A malignant kidney tumor, caused by the uncontrolled multiplication of renal stem (blastemal), stromal (STROMAL CELLS), and epithelial (EPITHELIAL CELLS) elements. However, not all three are present in every case. Several genes or chromosomal areas have been associated with Wilms tumor which is usually found in childhood as a firm lump in a child's side or ABDOMEN. [from MeSH]

2-hydroxyglutaric aciduria

2-Hydroxyglutaric aciduria is a group of neurometabolic disorders with a wide clinical spectrum ranging from severe neonatal presentations to progressive forms, and asymptomatic cases, characterized biochemically by increased levels of 2-hydroxyglutaric acid in the plasma, cerebrospinal fluid and urine. [from ORDO]

Wilms tumor 1

Aniridia is characterized by complete or partial iris hypoplasia usually (but not always) with associated foveal hypoplasia resulting in reduced visual acuity and nystagmus presenting in early infancy. Frequently associated ocular abnormalities (often of later onset) include cataract, glaucoma, and corneal opacification and vascularization. Aniridia may occur either as an isolated ocular abnormality without systemic involvement, caused by mutation of PAX6 or deletion of a regulatory region controlling its expression, or as part of the Wilms tumor-aniridia-genital anomalies-retardation (WAGR) syndrome, with a deletion of 11p13 involving the PAX6 (aniridia) locus and the adjacent WT1 (Wilms tumor) locus. Individuals with deletion of PAX6 and WT1 are at up to a 50% risk of developing Wilms tumor. [from GTR]

Combined d-2- and l-2-hydroxyglutaric aciduria

Combined D-2- and L-2-hydroxyglutaric aciduria (D-2-HG and L-2-HG) is an autosomal recessive neurometabolic disorder characterized by neonatal-onset encephalopathy with severe muscular weakness, intractable seizures, respiratory distress, and lack of psychomotor development resulting in early death. Brain imaging shows abnormalities including enlarged ventricles, delayed myelination, and germinal layer cysts (summary by Muntau et al., 2000). See also isolated L-2-hydroxyglutaric aciduria (236792) and isolated D-2-hydroxyglutaric aciduria (see 600721). [from GTR]

L-2-hydroxyglutaric aciduria

2-hydroxyglutaric aciduria is a condition that causes progressive damage to the brain. The major types of this disorder are called D-2-hydroxyglutaric aciduria (D-2-HGA), L-2-hydroxyglutaric aciduria (L-2-HGA), and combined D,L-2-hydroxyglutaric aciduria (D,L-2-HGA).The main features of D-2-HGA are delayed development, seizures, weak muscle tone (hypotonia), and abnormalities in the largest part of the brain (the cerebrum), which controls many important functions such as muscle movement, speech, vision, thinking, emotion, and memory. Researchers have described two subtypes of D-2-HGA, type I and type II. The two subtypes are distinguished by their genetic cause and pattern of inheritance, although they also have some differences in signs and symptoms. Type II tends to begin earlier and often causes more severe health problems than type I. Type II may also be associated with a weakened and enlarged heart (cardiomyopathy), a feature that is typically not found with type I.L-2-HGA particularly affects a region of the brain called the cerebellum, which is involved in coordinating movements. As a result, many affected individuals have problems with balance and muscle coordination (ataxia). Additional features of L-2-HGA can include delayed development, seizures, speech difficulties, and an unusually large head (macrocephaly). Typically, signs and symptoms of this disorder begin during infancy or early childhood. The disorder worsens over time, usually leading to severe disability by early adulthood.Combined D,L-2-HGA causes severe brain abnormalities that become apparent in early infancy. Affected infants have severe seizures, weak muscle tone (hypotonia), and breathing and feeding problems. They usually survive only into infancy or early childhood. [from GTR]
