| Gene |
HMBS |
| Chromosomal Location |
11q23.3 |
| Allelic Variant 1 |
A11A; PORPHYRIA, ACUTE INTERMITTENT |
| Identified Mutation |
ALA11ALA |
| Remarks |
Deficient uroporphyrinogen-I synthetase; active AIP; similarly affected sister; donor subject is heterozygous for a G>C transversion at nucleotide 33 in exon 1 of the HMBS gene (33G>C) resulting in the substitution of alanine for alanine at codon 11 [Ala11Ala (A11A)] |
