Description

Hyperphosphatasia with mental retardation syndrome-6 (HPMRS6) is an autosomal recessive multisystem disorder characterized by global developmental delay, dysmorphic features, seizures, and congenital cataracts. Severity is variable, and the disorder may show a range of phenotypic and biochemical abnormalities, including increased serum alkaline phosphatase levels (summary by Ilkovski et al., 2015). The disorder is caused by a defect in glycosylphosphatidylinositol (GPI) biosynthesis.For a discussion of genetic heterogeneity of HPMRS, see HPMRS1 (OMIM ).For a discussion of genetic heterogeneity of GPI biosynthesis defects, see GPIBD1 (OMIM ).
