Among such genes there are 10 which expression is significantly changed in 9 or more (out of 11) MPS types/subtypes; they include IER3IP1, SAR1A, TMEM38B, PLCB4, SIN3B, ABHD5, SH3BP5, CAPG, PCOLCE2, and MN1. Moreover, there are several genes whose expression is changed over log2 > 4 times in some MPS types relative to control cells. This evidence concerns the gene ABHD5 and mucopolysaccharidosis.
