Glycine encephalopathy is a rare autosomal recessive disorder of glycine metabolism. After phenylketonuria, glycine encephalopathy is the second most common disorder of amino acid metabolism. The disease is caused by defects in the glycine cleavage system, an enzyme responsible for glycine catabolism. There are several forms of the disease ...
It is a hypersensitivity to ingesting compounds in soy (Glycine max), causing an overreaction of the immune system, typically with physical symptoms, such as gastrointestinal discomfort, respiratory distress, or a skin reaction. [2] [3] Soy is among the eight most common foods inducing allergic reactions in children and adults. [1]
The three main signs of hyperekplexia are generalized stiffness, excessive startle response beginning at birth, and nocturnal myoclonus. [5] Affected individuals are fully conscious during episodes of stiffness, which consist of forced closure of the eyes and an extension of the extremities followed by a period of generalised stiffness and uncontrolled falling at times.

People with hypermethioninemia often do not show any symptoms. Some individuals with hypermethioninemia exhibit learning disabilities, mental retardation, and other neurological problems; delays in motor skills such as standing or walking; sluggishness; muscle weakness; liver problems; unusual facial features; and their breath, sweat, or urine may have a smell resembling boiled cabbage.
In mature adults, glycine is a inhibitory neurotransmitter found in the spinal cord and regions of the brain. [15] As it binds to a glycine receptor, a conformational change is induced, and the channel created by the receptor opens. [17] As the channel opens, chloride ions are able to flow into the cell which results in hyperpolarization.
That is roughly 16 mL of 50% ethylene glycol for an 80 kg adult and 4 mL for a 20 kg child. Poison control centers often use more than a lick or taste in a child or more than a mouthful in an adult as a dose requiring hospital assessment. [17] The orally lethal dose in humans has been reported as approximately 1.4 mL/kg of pure ethylene glycol. [7]
Glycine is a required co-agonist along with glutamate for NMDA receptors. In contrast to the inhibitory role of glycine in the spinal cord, this behaviour is facilitated at the glutamatergic receptors which are excitatory. [41] The LD 50 of glycine is 7930 mg/kg in rats (oral), [42] and it usually causes death by hyperexcitability. [citation ...
Signs of folate deficiency anemia most of the time are subtle. [4] Anemia (macrocytic, megaloblastic anemia) can be a sign of advanced folate deficiency in adults. [1] Folate deficiency anemia may result in feeling tired, weakness, changes to the color of the skin or hair, open sores on the mouth, shortness of breath, palpitations, lightheadedness, cold hands and feet, headaches, easy bleeding ...
