Visual impairment was present due to the presence of both cataracts and retinal dysfunction. [ncbi.nlm.nih.gov]

Genetic counseling GLUT1 deficiency syndrome is transmitted as an autosomal dominant trait and in these cases the affected parent presents with a mild form of the disease. [orpha.net]

• Babinski Sign

  Signs and symptoms generally develop within the first few months of life and may include recurrent seizures ( epilepsy ) and involuntary eye movements. [rarediseases.info.nih.gov]

• Spastic Gait

  The majority of subjects exhibit some kind of gait disturbance which varies in severity from mild ataxia to a spastic gait and inhibition of independent walking ability. [epilepsy.com]

While 9 out of 10 patients with GLUT1-DS became seizure-free with dietary treatment, only 3 out of the 33 remaining patients were seizure-free with KD or MAD treatment. [ncbi.nlm.nih.gov]

In particular, UX007 is proposed as an alternative treatment in patients who are not on, or not compliant with, a ketogenic diet. [epilepsy.com]

Recognizing these particular ocular movements would allow an early diagnosis, followed by ketogenic diet implementation, improving significantly the prognosis and the neurological development of those children. [ncbi.nlm.nih.gov]

Affected individuals should talk to their physician and medical team about their specific case, associated symptoms and overall prognosis. [checkorphan.org]

"These factors were correlated in a predictive mathematical model designed to guide prognosis on the basis of clinical features at diagnosis," he added. [sciencedaily.com]

Since early diagnosis and prompt implementation of the KD is believed to improve the long-term prognosis of patients with Glut1 DS, it is vital that neurologists recognize these episodes as an early diagnostic clue to the disease. [doi.org]

Etiology In the majority of cases the disease is associated with de novo mutations in the SLC2A1 gene. Diagnostic methods Diagnosis is based on the clinical picture and biochemical analysis of the cerebrospinal fluid (CSF). [orpha.net]

Patients and their families are given the opportunity to participate in research on a cellular and clinical level so that advances can be made in understanding the etiology and clinical course of particular disease pathways. [giblinlab.org]

The underlying pathophysiology for this phenomenon in GLUT1DS is not known, but may relate to cortical energy failure or abnormal cerebral microvasculature. [ncbi.nlm.nih.gov]

His translational research-oriented laboratory focuses on autoimmune mechanisms in autism, PANDAS, the neurobiology of tics, and the pathophysiology of stereotypic movements in animal models. [books.google.com]

The pathophysiologic mechanism underlying paroxysmal eye–head gaze saccades in Glut1 DS is unknown. [doi.org]

Studies to define the temporal requirements for Glut1 reveal that pre-symptomatic, AAV9-mediated repletion of the protein averts brain microvasculature defects and prevents disease, whereas augmenting the protein late, during adulthood, is devoid of benefit [escholarship.umassmed.edu]

Through a combination of laboratory studies, natural history studies, and therapeutic trials, the goal of the Colleen Giblin Research Laboratories is to provide a scientific foundation for ultimately finding more effective treatments and preventive therapies [giblinlab.org]
