Nature Lond ; Fine motor deficits may affect speech quality and manipulative skills, such as writing. De Vivo’s syndrome, described in convulsive infants with hypoglycorrachia during normoglycaemia, has been attributed to a reduction in the GLUT1 content in endothelial cells at the blood-brain barrier.

Glut1 deficiency

GLUT1 deficiencyalso known as De Vivo diseaseis an autosomal dominantgenetic metabolic disorder associated with a deficiency of GLUT1the protein that transports glucose across the blood brain barrier [1] also known as Glucose transporter type 1 deficiency syndrome GLUT1-DS. Seizure frequency is variable and a history of decreasing frequency deficienciq times of ketosis may prompt a diagnosis. Therapies and rehabilitative services are beneficial since most Glut1 Deficiency patients experience movement disturbances as well as speech and language disorders.

These abnormalities may be constant or intermittent paroxysmal.

Regulation of expression of glucose transporters by glucose: In obesity, the GLUT4 content is not diminished providing that insulin sensitiveness is preserved. Physiopathological changes in glucose transport started to be analysed through transporters with a view to future preventive or therapeutic approaches.

Horm Metab Deficiendia ; Genetic counseling GLUT1 deficiency syndrome is transmitted as an autosomal dominant trait and in these cases the affected parent presents with a defidiencia form of the disease. Extensive studies have been conducted to assess the role of GLUT4 in changes related to insulin sensitiveness, such as diabetes mellitus type 2 DM2.

Am J Physiol ; The disease causes infantile seizures refractory to anticonvulsive drugs, developmental delay, acquired microcephaly and neurologic manifestations including spasticity, hypotonia, and ataxia.

Most seizures in Glut1 Deficiency patients are not easily treated with anti-seizure medications. The ketogenic diet must be carefully crafted and tailored to meet the needs of each patient and reduce the risk of side effects.
