Delineation of PIGV mutation spectrum and associated phenotypes in hyperphosphatasia with mental retardation syndrome.
Krawitz et al., Berlin, Germany. In Eur J Hum Genet, 2014
Three different genes of the glycosylphosphatidylinositol anchor synthesis pathway, PIGV, PIGO, and PGAP2, have recently been implicated in hyperphosphatasia-mental retardation syndrome (HPMRS), also known as Mabry syndrome, a rare autosomal recessive form of intellectual disability.
Mutations in PGAP3 impair GPI-anchor maturation, causing a subtype of hyperphosphatasia with mental retardation.
Krawitz et al., Ōsaka, Japan. In Am J Hum Genet, 2014
Taken together with recent data on PGAP2, these results confirm the importance of the later GPI-anchor remodelling steps for normal neuronal development.
PIGO mutations in intractable epilepsy and severe developmental delay with mild elevation of alkaline phosphatase levels.
Saitsu et al., Yokohama, Japan. In Epilepsia, 2014
Among them, mutations in PIGV and PIGO, which are involved in the late stages of GPI-anchor synthesis, and PGAP2, which is involved in fatty-acid GPI-anchor remodeling, are all causative for hyperphosphatasia with mental retardation syndrome (HPMRS).
Hypomorphic mutations in PGAP2, encoding a GPI-anchor-remodeling protein, cause autosomal-recessive intellectual disability.
Abou Jamra et al., Copenhagen, Denmark. In Am J Hum Genet, 2013
PGAP2 encodes a protein involved in remodeling the glycosylphosphatidylinositol (GPI) anchor in the Golgi apparatus.
PGAP2 mutations, affecting the GPI-anchor-synthesis pathway, cause hyperphosphatasia with mental retardation syndrome.
Horn et al., Berlin, Germany. In Am J Hum Genet, 2013
We developed a diagnostic gene panel for targeting all known genes encoding proteins in the GPI-anchor-synthesis pathway to screen individuals matching these features, and we detected three missense mutations in PGAP2, c.46C>T, c.380T>C, and c.479C>T, in two unrelated individuals with hyperphosphatasia with mental retardation syndrome (HPMRS).
Enhanced response of T lymphocytes from Pgap3 knockout mouse: Insight into roles of fatty acid remodeling of GPI anchored proteins.
Murakami et al., Japan. In Biochem Biophys Res Commun, 2012
Fatty acid remodeling of GPI-APs in the Golgi apparatus is required for their efficient association with lipid rafts, i.e., the unsaturated fatty acid at the sn-2 position of the PI moiety is exchanged for the saturated fatty acid by PGAP2 and PGAP3.
