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 |

171760.0004; HYPOPHOSPHATASIA, INFANTILE |
| Identified Mutation |
ARG54PRO; In cell line GM03859, Henthorn et al. [Proc. Nat. Acad. Sci. 89: 9924-9928 (1992)] found compound heterozygosity for an arg54-to-pro mutation and a gln190-to-pro mutation (171760.0005). |

171760.0005; HYPOPHOSPHATASIA, INFANTILE |
| Identified Mutation |
GLN190PRO; In cell line GM03859, Henthorn et al. [Proc. Nat. Acad. Sci. 89: 9924-9928 (1992)] found compound heterozygosity for an arg54-to-pro mutation (171760.0004) and a gln190-to-pro mutation. |
| Remarks |
Severe, in utero onset; deficient liver, bone, and fibroblast alkaline phosphatase activity; donor subject is a compound heterozygote for two mutations in the ALPL gene: one allele carries an arg54-to-pro mutation [Arg54Pro (R54P)] and a second allele carries a gln190-to-pro mutation [Gln190Pro (Q190P)]. |
