We report a case of Gitelman syndrome presenting with fatigue, paresthesias, weakness of limbs and neck muscles since 2.5 years of age. Investigations showed hypokalemia and hypomagnesemia with urinary magnesium wasting. Genetic analysis revealed the presence of a novel homozygous mutation in the SLC12A3 gene (c.2879_2883+9ins14bp, p.Val 960 Glu fsx12). Management with potassium and magnesium supplements and spironolactone resulted in a significant improvement in symptoms. Over a follow-up of 11 years, the patient showed satisfactory growth and physical development.
