Inherited glycosylphosphatidylinositol biosynthesis deficiency (GPIBD) is a group of glycosylation disorders, which result from mutation in genes involved in the biosynthesis of GPI anchors. Mutations in several genes have been identified, mostly related to autosomal recessive. Clinical phenotypes are variable, often include developmental delay, hyperphosphatasia, (neonatal) seizures, hypotonia, neurological symptoms, growth abnormalities, and congenital abnormalities.
