Giant axonal neuropathy is a rare neuropathy that severely affects the peripheral as well as the central nervous system. The first symptoms appear in early childhood. This disorder is characterized by abnormalities in the peripheral and central nervous systems including low muscle tone (hypotonia), muscle weakness, decreased reflexes, impaired muscle coordination (ataxia), seizures and intellectual disability. Pale, tightly curled hair is freq  Read More

Congenital muscular dystrophy in its most severe form, hard +/-e syndrome, is accompanied by abnormalities of the brain and eyes. Typical signs and symptoms include hypotonia, muscle weakness, developmental delay, intellectual dysfunction, and sporadically occurring seizures. Lissencephaly, hydrocephalus, cerebellar deformities, eye abnormalities, and other abnormalities are also linked to it. Although the genetic etiology is  Read More

When a person has holocarboxylase synthetase deficiency, their body is unable to metabolize proteins and carbs. Biotin is a vitamin that aids in the body's conversion of specific carbs and proteins into energy; however, people with this illness have difficulty utilizing it. Because it can result in a dangerous accumulation of organic acids and toxins in the body, holocarboxylase synthetase deficiency is regarded as an organic  Read More

Propionic Acidemia is a rare metabolic disorder characterized by deficiency of propionyl CoA carboxylase, an enzyme involved in the breakdown (catabolism) of the chemical "building blocks" (amino acids) of certain proteins. Symptoms most commonly become apparent during the first weeks of life and may include abnormally diminished muscle tone (hypotonia), poor feeding, vomiting, listlessness (lethargy), excessive loss of fluids from bodily tiss  Read More

Succinic semialdehyde dehydrogenase (SSADH) deficiency is a rare inborn error of metabolism that is inherited as an autosomal recessive trait. In individuals with the disorder, deficient activity of the SSADH enzyme disrupts the metabolism of gamma-aminobutyric acid (GABA). GABA is a natural chemical known as a "neurotransmitter" that serves to inhibit the electrical activities of nerve cells (inhibitory neurotransmitter). SSADH deficiency lea  Read More
