Thus, they pose great diagnostic challenge to treating clinicians. Differentiating between the two conditions requires a battery of tests from screening to molecular diagnosis. Besides discussing differential diagnosis of MPS like features with negative urinary Glycosaminoglycans (GAG), the authors also discuss the utility of p-nitrocatechol sulphate based chemical test as an important screening tool, besides establishing molecular basis in index case.engGNPTABMucolipidosis type II alpha/beta (ML II alpha/beta)p-nitrocatechol sulphate (p-NCS)Molecular characterizationDoenças Genéticasjournal article10.1007/s12098-016-2243-7
