HK1

hexokinase 1

Gene Function

Catalyzes the phosphorylation of various hexoses, such as D-glucose, D-glucosamine, D-fructose, D-mannose and 2-deoxy-D-glucose, to hexose 6-phosphate (D-glucose 6-phosphate, D-glucosamine 6-phosphate, D-fructose 6-phosphate, D-mannose 6-phosphate and 2-deoxy-D-glucose 6-phosphate, respectively). Does not phosphorylate N-acetyl-D-glucosamine. Mediates the initial step of glycolysis by catalyzing phosphorylation of D-glucose to D-glucose 6-phosphate (By similarity). Involved in innate immunity and inflammation by acting as a pattern recognition receptor for bacterial peptidoglycan. When released in the cytosol, N-acetyl-D-glucosamine component of bacterial peptidoglycan inhibits the hexokinase activity of HK1 and causes its dissociation from mitochondrial outer membrane, thereby activating the NLRP3 inflammasome Source: UniProt

ClinVar Variants

Pathogenic and likely pathogenic variants in HK1, as classified in ClinVar, are read live from NCBI. Only aggregate germline records are shown. 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.

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, one for a single submitter with criteria provided, and none where no criteria were provided.

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.

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.
