nucSEEK® Focus Nuclear Mitochondrial Gene Panel

Mitochondrial disorders are very diverse conditions and can affect one or multiple systems of the body. Mitochondrial dysfunction depletes cells of energy causing cell damage and even cell death. There are hundreds of genes in the nuclear DNA found to have an association with mitochondrial dysfunction. Courtagen’s nucSEEK® Focus test uses Next Generation Sequencing to detect variants in these nuclear genes to add value in obtaining a definitive diagnosis, estimating prognosis, guiding treatment choices, and determining recurrence risks.

Del/Dup Additional Analysis (181 genes): Additional analysis of exon-sized (and larger) deletion and duplication variants in 182 genes is available as an add-on for both the nucSEEK Focus and nucSEEK Comprehensive panels.
