IthaID: 3443

Context nucleotide sequence:
GGGATATTATGAAGGGCCTTGAGCATC [T>C] GGATTCTGCCTAATAAAAAACATTTATT (Strand: -)

Also known as:

Comments: The mutation is located 12 nucleotides upstream of the polyadenylation signal in the 3' UTR of the β-globin gene. In heterozygous carriers, the mutation causes a silent phenotype, while in compound heterozygosity with severe beta-thal mutations, it leads to a beta-thal intermedia state.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
