| Identified Mutation |
ARG195CYS |
| Remarks |
See GM00939 Fibroblast; deficient uroporphyrinogen-I synthetase; active AIP; Neutral Alpha-glucosidase C phenotype=1; positive family history; donor subject is heterozygous for a C>T transition at nucleotide 583 in exon 10 of the HMBS gene (583C>T) resulting in the substitution of cysteine for arginine at codon 195 [Arg195Cys (R195C)] |
