The purpose of this study is to assess the frequency of Fabry disease in children with early symptoms.

Fabry disease is a complex, multisystemic and clinically heterogeneous disease that commonly presents in childhood and is caused by deficient activity of the lysosomal enzyme alpha-galactosidaseA (α-gal A). Symptoms of Fabry disease in the pediatric population are well described. Symptoms can occur in early childhood, before age 5 years. Incidence estimations of Fabry disease vary widely. The true incidence is likely to be higher than originally thought, owing to the existence of milder variants of the disease. The purpose of this study is to assess the frequency of Fabry disease in children with early symptoms. Patients would benefit from early diagnosis, appropriate treatment, follow-up and surveillance. Early detection of Fabry patients would also benefit affected relatives, many of whom do not have a clear diagnosis of their clinical condition.

Inclusion Criteria:

• Patients with fabry disease-associated phenotypes in infancy, childhood and adolescence: pain in the hands and feet, angiokeratomas, hypohidrosis, corneal whorls, unexplained renal failure, unexplained hypertrophic myocardiopathy and unexplained early onset stroke.

Exclusion Criteria:

• Patient's parent(s) or legal guardian(s) are unable to understand the nature, scope, and possible consequences of the screening.
