GABA transaminase deficiency. Case report and literature review

Area of Science:

• Neurology
• Metabolic Disorders
• Genetics

Background:

• Early-onset epileptic encephalopathies represent a diagnostic challenge.
• Neurometabolic disorders are often rare and difficult to identify.
• GABA transaminase deficiency is a specific, treatable cause of these conditions.

Observation:

• A case study highlighted the post-mortem diagnosis of GABA transaminase deficiency in an infant.
• The diagnosis occurred within a family with a history of unexplained infant neurological issues.
• This rare neurometabolic disorder presented as severe epilepsy.

Findings:

• GABA transaminase deficiency was confirmed as the cause of the infant's neurological condition.
• The diagnosis was established through post-mortem examination.
• Genetic analysis confirmed the specific deficiency.

Implications:

• Increased vigilance for GABA transaminase deficiency can lead to earlier diagnoses in affected infants.
• Genetic counseling is vital for families with rare neurometabolic disorders.
• Reproductive options, such as pre-implantation genetic diagnosis, can be offered to at-risk families.
