Peroxisomal Disorders: Experience from a Genetic Center in North India

Abstract

Diagnosis of peroxisomal disorders (PDs) is often delayed because of unfamiliarity with the characteristic features of PDs and their genetic heterogeneity. Aim of this study was to describe clinical profiles of six children with PDs. This is a retrospective study involving six children with PDs. The patients included three males, one female, and a fetus. Three patients were diagnosed with Zellweger's syndrome, two with rhizomelic chondrodysplasia punctata, and one with X-linked adrenoleukodystrophy. These diagnoses were established based on clinical, radiological, and biochemical features (elevated very long chain fatty acids levels). Parents of all cases have been provided genetic counseling and advised of prenatal diagnosis. Diagnosis of PDs requires knowledge of characteristic clinicoradiological features, and clinical confirmation is possible with simple imaging and biochemical investigations. Molecular diagnosis is possible for selected cases.
