ALPL |
Chromosomal Location |
1p36.1-p34 |
Allelic Variant 1 |
171760.0002; HYPOPHOSPHATASIA, INFANTILE |
Identified Mutation |
ARG54CYS; In studies of fibroblasts from 4 unrelated patients with severe (perinatal or infantile) hypophosphatasia (241500), Henthorn et al. [Proc. Nat. Acad. Sci. 89: 9924-9928 (1992)] identified a different mutation in each of the 8 ALPL alleles, indicating that all were genetic compounds. They found 2 linked polymorphisms in 1 allele of each patient. One allele found in cell line GM04235 was a C-to-T transition at nucleotide 387 in exon 4 leading to substitution of cysteine for arginine at amino acid 54. |
Remarks |
Clinically normal; low serum alkaline phosphatase level; 2 affected children |
