Mitochondrial Disease Panel

The Blueprint Genetics Mitochondrial Disorders Panel is a comprehensive genetic test designed to detect variants in mitochondrial DNA (mtDNA) and mutations in nuclear DNA associated with mitochondrial diseases. These conditions are complex and can affect multiple organ systems, including muscles, nerves, heart, and brain.

Overview

Mitochondria perform various functions across the body’s tissues. Therefore, the clinical spectrum of mitochondrial disorders is diverse, with symptoms ranging from fatigue and exercise intolerance to developmental delay, hearing loss, seizures, strokes, heart failure, diabetes, and kidney failure.

Mitochondrial disorders may not be identified solely through nuclear gene sequencing. The combination of nuclear and mitochondrial DNA testing is a powerful tool for patients with clear genetic conditions where nuclear DNA sequencing could yield negative results.

It is estimated that mitochondrial diseases affect about 1 in 5,000 people worldwide, representing a significant population in a country as large as Brazil.

When Should You Consider This Test?

Consider this test in the following cases:

Unexplained Muscle Weakness
Exercise Intolerance
Seizures
Developmental delay
Multiorgan Failure
Persistent Lactic Acidosis
Recurrent Strokes or Unexplained Heart Problems

Genes Analyzed

The panel includes:

+300

Genes

It includes both mitochondrial and nuclear genes. Examples of genes covered are:

  • MT-ATP8, MT-ND1, MT-CO1, POLG, and OPA1, associated with conditions such as mitochondrial myopathies, Leber’s hereditary optic neuropathy (LHON), and progressive external ophthalmoplegia.
  • In total, more than 300 genes relevant to mitochondrial function are analyzed.
