Fabry disease is an X-linked lysosomal disease caused by deficiency of alpha-galactosidase A. Signs and symptoms of Fabry disease occurring during childhood and adolescence were characterized in 352 Fabry Registry patients. At enrollment (median age 12 year), 77% of males and 51% of females reported symptoms. The median age of symptom onset was 6 year in males and 9 year in females. The most frequent symptom, neuropathic pain, was reported by 59% of males (median age 7 year) and 41% of females (median age 9 year). Gastrointestinal symptoms were reported by 18% of children (median age 5 year in males and 9.5 year in females). Males exhibited height and weight values below the US 50th percentile. Females had weight values above the US 50th percentile. A few patients had serious renal and cardiac manifestations, stage 2 or 3 chronic kidney disease (n = 3), arrhythmia (n = 9), and left ventricular hypertrophy (n = 3). Thus, many pediatric Fabry patients report early symptoms, particularly pain, gastrointestinal symptoms, and impaired quality of life. Some children experience major complications during the pediatric years.
