Trait
Nevus anemicus
A congenital skin lesion characterized by irregular hypopigmented macules that coalesce to form plaques and occur particularly on the chest. It is generally present at birth or develops in the first days of life. It is more common in females. Diagnosis is confirmed by applying gentle friction to the lesion and the surrounding skin and checking that the erythema produced in the healthy skin does not appear in the hypopigmented lesion. This pale macule becomes more conspicuous when the lesion and its surroundings are rubbed. The margin of the naevus is ill-defined and consists of an archipelago of small anemic spots.

Changes in these genes cause rare conditions in which Nevus anemicus 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 |
|---|---|---|
| NF1neurofibromin 1 | Often (30–79%) | 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.
