Common Name: CD 124 (-C) HGVS Name: HBB:c.374delC
Hb Name: N/A Protein Info: N/A

Context nucleotide sequence:
CATCACTTTGGCAAAGAATTCACCC [C/-] ACCAGTGCAGGCTGCCTATCAGAAA (Strand: -)

Also known as:

Comments: A 'C' deletion in exon 3 of HBB resulting in a frameshift and a predicted production of β-globin chains with an elongated C-terminus. Found in a heterozygous state in four affected individuals from one family, showing hypochromic microcytic anemia accompanied by increased ferritin levels and Coombs-negative hemolysis.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
