gene mutations and are inherited in an autosomal recessive pattern, except for a D-2HGA subtype, known as type II D-2-HGA, which is inherited in an autosomal dominant pattern.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 vary within the different types but, in general, may include 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. The different types and subtypes are caused by different
