Pseudoxanthoma elasticum epidemiology and demographics

Introduction

Overview

Overview

Published reports estimate that the prevalence of pseudoxanthoma elasticum, both the recessive and dominant forms, is 1 in 70,000 to 100,000,[1] with females twice as many as the males.

Epidemiology and Demographics

Epidemiology and Demographics

Pseudoxanthoma elasticum (PXE) is a rare disease but the exact prevalence is unknown. The prevalence has been suggested to be approximately 1:50,000, with an estimate of 150,000 affected in the world assuming the same global prevalence.[2] Females are twice as likely to be affected as males, and the average age of onset is 13 years. The disease occurs in all ethnicities, and an increased risk for PXE is seen in a few populations including the Afrikaners in South Africa, who display a founder effect.[3][4]
