The same "TATA" box beta-thalassemia mutation in Chinese and US blacks: another example of independent origins of mutation. 1986

S Huang, and C Wong, and S E Antonarakis, and T Ro-lien, and W H Lo, and H H Kazazian

A Chinese beta +-thalassemia gene in a new haplotype was chosen for cloning and sequencing. The mutation identified was an A-G transition at position -29 in the TATA box of the beta-globin gene. This mutation has not been seen previously in Chinese but has been documented in American blacks on a different chromosomal background. This observation provides further evidence for independent origins of the same mutation in distinct ethnic groups.

UI MeSH Term Description Entries
D009154 Mutation Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations. Mutations
D002681 China A country spanning from central Asia to the Pacific Ocean. Inner Mongolia,Manchuria,People's Republic of China,Sinkiang,Mainland China
D004262 DNA Restriction Enzymes Enzymes that are part of the restriction-modification systems. They catalyze the endonucleolytic cleavage of DNA sequences which lack the species-specific methylation pattern in the host cell's DNA. Cleavage yields random or specific double-stranded fragments with terminal 5'-phosphates. The function of restriction enzymes is to destroy any foreign DNA that invades the host cell. Most have been studied in bacterial systems, but a few have been found in eukaryotic organisms. They are also used as tools for the systematic dissection and mapping of chromosomes, in the determination of base sequences of DNAs, and have made it possible to splice and recombine genes from one organism into the genome of another.
