ClinVar Variants

Pathogenic and likely pathogenic variants in PDK3, as classified in ClinVar, are read live from NCBI.

Reported in CMT
Reported in Other Diseases

Reported in a disease other than CMT. Listed apart rather than counted as CMT variants.

Variants w/o a Recorded Disease

Pathogenic or likely pathogenic in ClinVar, submitted without a disease recorded.

What the review stars mean

Review stars are ClinVar’s measure of how well a classification is supported: four for a practice guideline, three for an expert panel review, two for agreement among multiple submitters, and one for a single submitter with criteria provided. A record with no criteria provided earns no stars and is not indexed.

Only aggregate germline records are indexed. Uncertain and conflicting classifications are not. Experts in CMT makes no claim to the accuracy of ClinVar data. This index is provided for informational purposes only.

Gene Function

PDK3 inhibits pyruvate dehydrogenase activity by phosphorylation of the E1 subunit PDHA1, and thereby regulates glucose metabolism and aerobic respiration. Can also phosphorylate PDHA2. Decreases glucose utilization and increases fat metabolism in response to prolonged fasting, and as adaptation to a high-fat diet. Plays a role in glucose homeostasis and in maintaining normal blood glucose levels in function of nutrient levels and under starvation. Plays a role in the generation of reactive oxygen species Source: UniProt

A Name That Does Too Much Work

Jean-Martin Charcot's name appears throughout medicine, but nowhere does it create more confusion than in the foot. Learn why the CMT foot and Charcot neuroarthropathy, also known as Charcot foot, share a name yet differ in how they develop, appear, and are managed.


When Medicine Lost Its Compass

Evidence failed not because it was wrong, but because it was weaponized. I lived the downstream effects of that failure for more than a decade. This is what happens when medicine forgets that data always ends in a human being.


Error 404: Gene Not Found

CMT genetic testing often fails to identify the cause of the disease, even when comprehensive panels are used. Here, we discuss why this happens, what genetic tests can and cannot do, and why a negative result still matters.
