IthaID: 4153

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: N/A
Common Name: -206 C>G HGVS Name: HBB:c.-256C>G
Hb Name: N/A Protein Info: N/A
Also known as:

We follow the HGVS sequence variant nomenclature and IUPAC standards.

Context nucleotide sequence:
CAATTTGTACTGATGGTATGGGGC [C/G] AAGAGATATATCTTAGAGGGAGGGC (Strand: -)

Comments: Identified in two adult males during thalassemia screening. DNA analysis in both individuals revealed compound heterozygosity for the -206 C>G variant and the known β⁺ variant -31 A>G in trans. This combination results in a β-thalassemia trait phenotype, suggesting that the -206 C>G variant is benign or likely benign.
