CONDITION REFERENCE

Rosacea

Information from MedlinePlus Genetics about this condition and how it can be inherited.

About this condition

Rosacea is a long-lasting (chronic) skin disease that affects the face, primarily the forehead, nose, cheeks, and chin. The signs and symptoms of rosacea vary, and they may come and go or change over time.

There are three main types of rosacea, categorized by their primary signs and symptoms. Erythematotelangiectatic rosacea causes skin redness and warmth (flushing) and visible clusters of blood vessels (telangiectasia). Papulopustular rosacea causes skin redness, swelling, and pus-filled bumps called pustules. Phymatous rosacea is characterized by thickened skin on the face and an enlarged, bulbous nose (rhinophyma). People with rosacea may feel itching, stinging, or burning sensations in affected areas. Often, the disorder affects the eyes, causing abnormal inflammation of the eyelids and eyes (ocular rosacea). This inflammation can cause dryness, redness, and irritation of the eyes and may affect vision.

YOUR DNA FILE

What can your DNA file tell you?

Your DNA file only includes the positions your test checked and reported. Consumer DNA kits usually test selected positions. Sequencing files can also leave out positions that were not reported or where the test could not give a result.

A variant missing from your file does not mean you tested negative for it. A ClinVar classification applies to a particular variant and the condition or finding it was reported for. It does not apply to everyone with that gene. An uncertain finding cannot establish a diagnosis.

BioDecode reads supported DNA files on your computer. It cannot fill gaps in your test, diagnose a condition or replace clinical testing.
