Trait
Prolonged central motor conduction time
Increased duration of the central motor conduction time (CMCT). The CMCT estimates the conduction time of corticospinal fibers between motor cortex and spinal (or bulbar) motoneurons. It includes the times for excitation of cortical cells, conduction via the corticobulbar-corticospinal tract and excitation of the motoneuron sufficient to reach its firing threshold. CMCT is calculated by subtracting the peripheral conduction time from the MEP latency recorded after cortical stimulation.

Changes in these genes cause rare conditions in which Prolonged central motor conduction time is seen. Most people with this trait have none of those conditions, and a gene on this list says nothing about anyone's own genome.
| Gene | How often it is seen | Conditions |
|---|---|---|
| CPT1Ccarnitine palmitoyltransferase 1C | Always | In 1 condition |
How often is among people with one of the gene's conditions, the most often across them, as the Human Phenotype Ontology records it. These pages describe traits and the research behind them; they are not a diagnosis, and a doctor or genetic counsellor is the person to ask about symptoms.
