Trait
Phonic tics
Tics are defined as movements or sounds that resemble physiological motor behaviors, but are typically inopportune to social context and appear sudden, repetitive, and often exaggerated. Tic vocalizations commonly termed vocal or phonic tics may include any possible sound (eg, sniffing, coughing, throat clearing, whistling, or grunting), word, or sentence and are most commonly encountered within the spectrum of primary tic disorders, as Tourette syndrome.

Changes in these genes cause rare conditions in which Phonic tics 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 |
|---|---|---|
| MOCS3molybdenum cofactor synthesis 3 | Always | In 1 condition |
| VPS13Avacuolar protein sorting 13 homolog A | Often (30–79%) | In 1 condition |
| GNB1G protein subunit beta 1 | Sometimes (5–29%) | In 1 condition |
| PANK2pantothenate kinase 2 | Sometimes (5–29%) | In 1 condition |
| SLITRK2SLIT and NTRK like family member 2 | Sometimes (5–29%) | In 1 condition |
| HDChistidine decarboxylase | Not recorded | In 1 condition |
| SLITRK1SLIT and NTRK like family member 1 | Not recorded | 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.
