Associated disorders

The CHCHD10 gene is associated with autosomal dominant frontotemporal dementia and/or amyotrophic lateral sclerosis 2 (FTDALS2) (MedGen UID: 797270), spinal muscular atrophy, Jokela type (SMAJ) (MedGen UID: 767312), and isolated mitochondrial myopathy (IMMD) (MedGen UID: 830724).

Invitae tests that include this gene:

CHCHD10 encodes a coiled coil-helix-coiled coil-helix protein that functions in the intermembrane space of the mitochondria. This protein is part of the MICOS complex, which is important for mitochondrial cristae maintenance and function and the proper organization of nucleoids and mitochondrial DNA integrity.

Assay and technical information

Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).

Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence, and select noncoding variants. Our assay provides a Q30 quality-adjusted mean coverage depth of 350x (50x minimum, or supplemented with additional analysis). Variants classified as pathogenic or likely pathogenic are confirmed with orthogonal methods, except individual variants that have high quality scores and previously validated in at least ten unrelated samples.

Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
