Similarly, mutations in 5’-phosphatase inositol polyphosphate 5-phosphatase K (INPP5K) result in the autosomal recessive MDCCAID (Muscular Dystrophy, Congenital, Cataracts And Intellectual Disability) disorder, where the patients suffer from mild intellectual disability in addition to the main symptoms of muscular dystrophy and early-onset cataract (Osborn et al., 2017; Wiessner et al., 2017). Here, INPP5K is linked to Intellectual disability.
