Halothane

Unable to determine

We couldn't check the genes for this anesthesia reaction from your data. This does not mean that a normal response is expected.

The genes behind this label

The guidelines read 2 genes for halothane. Each card shows the two copies this person inherited and what they mean.

Not checked

We couldn't check this gene from your data. This does not mean that a normal response is expected.

A muscle channel. Rare changes in it can cause a dangerous reaction to some anesthetics.

Not checked in this report, so its part in the label is unknown.

In plain words
We couldn't check the genes for this anesthesia reaction from your data. This does not mean that a normal response is expected.
What it means
Malignant hyperthermia susceptibility could not be determined.
What the guideline suggests
Clinical findings, family history and clinical evaluation should guide anesthesia decisions.

CPIC reads your RYR1 and CACNA1S results together for halothane, so this label reflects both genes.

About halothane

Halothane is an older potent volatile anesthetic and a malignant hyperthermia (MH) trigger in people who carry certain RYR1 or CACNA1S variants.

Used for
General anesthesia (now limited use); a reagent in the laboratory muscle test for MH
