Leigh syndrome, also known as Leigh disease, is a rare, severe neurological disorder that typically becomes apparent in infancy or early childhood. It is characterized by progressive loss of mental and movement abilities, leading to severe neurological disability and often death by two to three years of age. However, some affected individuals may have a milder course of the disease with later onset and longer survival. Leigh syndrome is genetically heterogeneous, meaning it can be caused by mutations in various genes, and it can be inherited in several different ways, depending on the gene involved:

• Mitochondrial DNA Mutations: Some cases of Leigh syndrome are caused by mutations in genes found within mitochondrial DNA (mtDNA), which is inherited maternally (only passed down from mothers)
• Nuclear DNA Mutations: More commonly, the mutations associated with Leigh syndrome are in genes located on nuclear DNA, which is inherited in an autosomal recessive pattern. This means that both copies of the gene in each cell have mutations.

The mutations responsible for Leigh syndrome typically impair the function of mitochondria, the energy-producing structures within cells. This often involves disruptions in oxidative phosphorylation, which is part of the mitochondrial energy generation process. The disruption results in widespread energy deficiencies, particularly affecting organs and tissues with high energy demands such as the brain, muscle, and heart.

Market Dynamics:

The global Leigh syndrome treatment market has been witnessing notable growth over the past few years owing to the rising prevalence of this rare neurological genetic disorder that is also referred to as subacute necrotizing encephalomyelopathy or Leigh disease. Leigh syndrome is a rare disorder characterized by bilateral lesions in the basal ganglia and brainstem that primarily affects the central nervous system and is a mitochondrial disease. It usually becomes evident in infancy or early childhood and can cause developmental delays or regression, movement problems, weakness, vision/hearing problems, and others. Increasing research activities to develop effective treatment options and rising awareness about this serious illness are fueling the market growth.

However, the market growth can be limited due to factors like high cost of treatment, availability of few approved treatment options, lack of disease-specific treatment, and difficulty in diagnosing this rare genetic disorder. Various opportunities for market players lie in developing novel drugs with improved efficacy, focusing on gene therapy and mitochondrial transplantation research, collaborating with clinical researchers, and expanding in emerging markets.
