Gene |
HBB |
Chromosomal Location |
11p15.5 |
Allelic Variant 1 |
141900.0364; BETA-PLUS-THALASSEMIA |
Identified Mutation |
IVS1, G>A, +110; A G-to-A change at position 110 of IVS-1 was found in a Mediterranean patient by Spritz et al. (1981) and Westaway and Williamson (1981). The mutation created a new splice acceptor site. Kaplan et al. (1990) studied the molecular basis of beta-thalassemia minor, which has a frequency of about 1% among French Canadians residing in Portneuf County of Quebec Province. They showed that there were 2 different beta-thalassemia mutations segregating in the population: an RNA processing mutation involving nucleotide 110 of IVS-1 on haplotype 1 and a point mutation leading to chain termination through a nonsense codon at position 39 (141900.0312), occurring on haplotype 2.
