Hyperphosphatasia With Mental Retardation Syndrome 4; Hpmrs4
Hyperphosphatasia with mental retardation syndrome-4 is an autosomal recessive neurologic disorder characterized by severely delayed psychomotor development, mental retardation, lack of speech acquisition, seizures, and dysmorphic facial features. Laboratory studies show increased serum alkaline phosphatase (summary by Howard et al., 2014). 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 ).
