INTRODUCTION: Lysosomal storage disorders (LSDs) are a heterogeneous group of large molecule inborn errors of metabolism, rather commonly seen by clinician.
OBJECTIVES: This study aims to highlight the more common type of LSDs, their frequency, clinical spectrum and outcome from Rare disease centre in Rajasthan.
METHODS: The retrospective data were collected including clinical profile, investigations, screening test and enzyme analysis results. All outcomes were recorded from follow-up clinic.
RESULTS: This cohort comprised 65 children with different type of LSDs including 54 males and 11 females. The average age of presentation of the LSD patients was 3.5 years (range 6 months to 13 years). Gaucher disease was the most commonly found LSD (46.1%) followed by mucopolysaccharidosis (35.3%). Common presentations among GD patients were anemia, thrombocytopenia, and abdominal distension due to splenohepatomegaly/hepatomegaly. Among MPS Disorder, MPS type 2 (Hunter syndrome) was the most common (39.1%), followed by MPS type 1(Hurler syndrome) (30%) and MPS type IVA (Morquio syndrome) (17.3%). Non GD non MPS group comprised most commonly of GM1 gangliosidosis followed by pompe disease, Metachromatic Leucodystrophy, Mucolipidosis type II (I cell disease), and Sandhoff disease.
CONCLUSIONS: LSDs comprises an important group of genetic metabolic disorders. Among these GD are the most common, followed by MPS.
