Weiss et al (Am J Hum Genet 44:686-694 1989) reported that this fibroblast culture from an individual affected with Hypophosphatasia had deficient liver/bone/kidney alkaline phosphatase activity but expressed apparently full-sized liver/bone/kidney mRNA at normal levels. Southern blot analysis of the liver/bone/kidney alkaline phosphatase gene revealed identical restriction patterns for this individual and normal controls. EC Number: 3.1.3.1 |
| |
| Remarks |
Fibroblasts show deficient LBK alkaline phosphatase activity; lethal, infantile form; passage 2 at CCR |
