Genomic Unity® Mitochondrial Genome Analysis

Test Description

Test Code – CP003

Mitochondrial disorders are a clinically diverse group of genetic conditions that affect the function of the mitochondria, the main source of energy for cells throughout the body. Multiple organ systems are typically affected in mitochondrial disorders, particularly the brain, skeletal and heart muscle, kidneys, and the endocrine system. These systems require large amounts of energy and tend to have the most mitochondria per cell. Mitochondrial disorders are hard to diagnose as they can affect each individual differently, leading to different symptoms from person to person.

Genomic Unity® Mitochondrial Genome Analysis is an effective test for identifying variants within the mitochondrial genome.

When to order

Order when clinical symptoms are consistent with or suggestive of a mitochondrial disorder. You also have the option to reflex to Genomic Unity® Exome Analysis or Genomic Unity® Exome Plus Analysis if targeted testing is non-diagnostic.
