    Mutations in the PIGV, PIGO, PIGL, PIGY, PGAP2, PGAP3, and PIGW genes have recently been reported to cause hyperphosphatasia accompanied by mental retardation syndrome (HPMRS); the latter is an autosomal-recessive neurological disorder ..

    ..We conclude that PIG-L, like a number of other ER membrane proteins, is retained in the ER through a multi-component localization signal rather than a discrete sorting motif. ..
