Hyperphosphatasia With Mental Retardation Syndrome 3; Hpmrs3
Hyperphosphatasia with mental retardation syndrome-3 is an autosomal recessive disorder usually characterized by severe mental retardation, hypotonia with very poor motor development, poor speech, and increased serum alkaline phosphatase (summary by Hansen et al., 2013). However, the severity of the disorder can also vary to include milder intellectual disability (Krawitz et al., 2013). 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 ).
