Introduction The mucopolysaccharidoses (MPSs) are a group of rare genetic lysosomal disorders with progressive multisystem involvement. An MPS-specific physical symptom scale was developed and introduced a Physical Symptom Score (PSS) to quantify the somatic disease burden across MPS I, II and VI. Hypothesis Somatic burden of disease in patients with attenuated MPS I, II and VI as measured by the PSS will be positively associated with age and negatively associated with neuropsychological functions [i.e. full scale intelligence quotient (FSIQ) and attention]. Materials and methods Forty-eight patients with attenuated MPS I (n = 24), II (n = 14), and VI (n = 10) aged 6 to 32 years on enzyme replacement therapy who were enrolled in “Longitudinal Studies of Brain Structure and Functions in MPS Disorders” across seven centers. Somatic disease burden was measured by the PSS. Neuropsychological functions were measured by the Wechsler Abbreviated Scale of Intelligence (WASI) and Test of Variables of Attention (TOVA). Results PSS was positively associated with age in attenuated MPS I (P, Highlights • MPS-specific physical symptom scale introduced a Physical Symptom Score (PSS) by quantifying the somatic disease burden • PSS was significantly positively associated with age in attenuated MPS I, MPS II and MPS VI • PSS was significantly negatively associated with Full Scale IQ (FSIQ) in attenuated MPS I and in MPS VI • PSS was not statistically significantly associated with FSIQ in MPS II, but had similar direction as other two groups • • There were no previous studies that examined the association of PSS in MPS disorders with neuropsychological functions
