Symptoms of SDHA Gene Leigh Syndrome Genetic Test

Leigh Syndrome, also known as Subacute Necrotizing Encephalomyelopathy, is a severe neurological disorder that typically arises in the first year of life. This condition, which can be linked to mutations in the SDHA gene among others, leads to progressive loss of mental and movement abilities, resulting in severe neurological and physical decline. Recognizing the symptoms early can be crucial for managing the condition. DNA Labs UAE offers a comprehensive genetic test for diagnosing mutations in the SDHA gene associated with Leigh Syndrome. This test is pivotal for families seeking answers to unexplained symptoms of neurological decline in their children.

Understanding Leigh Syndrome

Leigh Syndrome affects the central nervous system, comprising the brain, spinal cord, and optic nerves. It disrupts the mitochondria, the energy-producing structures within cells, leading to cell death in the brain, muscles, and heart. The condition is genetically inherited, usually through mutations in mitochondrial DNA, but can also be due to mutations in nuclear DNA, such as those in the SDHA gene.

Key Symptoms of Leigh Syndrome

Identifying Leigh Syndrome early in its course is critical for management and care. Symptoms vary widely among individuals but commonly include:

  • Psychomotor regression: A noticeable decline in physical movements and mental abilities.
  • Muscle weakness and hypotonia: Reduced muscle tone and strength, making movements difficult.
  • Ataxia: Lack of muscle coordination affecting speech, eye movements, and swallowing.
  • Breathing difficulties: Including irregularities such as apnea or rapid breathing.
  • Optic atrophy: Deterioration of the optic nerve, leading to vision problems.
  • Eating difficulties: Problems with swallowing or sucking, leading to poor growth.
  • Lactic acidosis: An abnormal increase in lactate in the blood, often leading to metabolic complications.
  • Neurological episodes: Seizures or periods of reduced consciousness.

These symptoms often progress rapidly, and early intervention is key to managing the condition.
