Trait
Sebaceous hyperplasia
A common, benign skin condition involving hypertrophy of the sebaceous glands characterized by single or multiple lesions that manifest as yellow, soft, small papules with umbilication. The lesions are located commonly on the central face (specifically, the nose, cheeks and forehead) but may also occur elsewhere, including the chest, mouth, scrotum, foreskin, penile shaft, vulva, and areola.

Changes in these genes cause rare conditions in which Sebaceous hyperplasia 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 |
|---|---|---|
| FLCNfolliculin | Sometimes (5–29%) | 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.
