Moreover, mutations in INPP5K, which encodes the inositol polyphosphate-5-phosphatase K, also known as SKIP (skeletal muscle and kidney enriched inositol phosphatase), cause congenital muscular dystrophy (Osborn et al., 2017; Wiessner et al., 2017), with LGMD and neuropathic features. This evidence concerns the gene INPP5K and limb-girdle muscular dystrophy.
