Genomic Unity® Mitochondrial Analysis

Mitochondrial disorders are a clinically heterogeneous group of genetic disorders that affect the function of proteins or RNA molecules that reside in the mitochondria, the main energy factory for cells throughout the body. In mitochondrial disorders multiple organ systems are typically involved, particularly the brain, skeletal muscle, heart, kidney and endocrine systems which require high amounts of energy and tend to have the greatest average number of mitochondria per cell. Mitochondrial disorders are particularly hard to diagnose as they can affect each individual differently, leading to very different presentations from patient to patient.

Genomic Unity^® Mitochondrial Analysis is an effective test for identifying the genetic cause underlying clinical symptoms consistent with a mitochondrial disorder.

When to order

Order this test when the patient presents with clinical symptoms affecting multiple organ systems and that are suggestive of a mitochondrial disorder, and you'd like the option to reflex up to Genomic Unity^® Exome Plus Analysis.

Or when you would like to pair analysis of the mitochondrial genome with another analysis due to shared clinical symptomology with mitochondrial disorders.

Included analyses

Sequencing analysis of nuclear mitochondrial genes

Del/dup analysis of nuclear mitochondrial genes

Mitochondrial genome analysis with heteroplasmy (≥5%)

Optionally includes:

Reflex to Genomic Unity^® Exome Plus Analysis
