Epileptic Encephalopathy Due to BRAT1 Pathogenic Variants

Area of Science:

• Genetics
• Neurology
• Pediatrics

Background:

• The BRAT1 gene plays a crucial role in cellular processes.
• Genetic variants can lead to severe developmental and neurological conditions.

Purpose of the Study:

• To investigate the role of compound heterozygous BRAT1 variants in a family with severe infantile disorders.
• To characterize the clinical presentation associated with these specific genetic variants.

Main Methods:

• Clinical case study of two affected siblings.
• Genetic analysis to identify variants in the BRAT1 gene.

Main Results:

• Identified compound heterozygous variants in the BRAT1 gene in both affected brothers.
• Observed variable clinical presentations including intractable epilepsy, poor development, microcephaly, hypertonia, apnea, and early death.

Conclusions:

• Compound heterozygous BRAT1 variants are associated with a severe neurodevelopmental disorder.
• BRAT1 variants represent a significant genetic cause of early-onset intractable epilepsy and developmental failure.
