IthaID: 3248

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: Variant of Uncertain Significance
Common Name: CD 13 GCC>GTC [Ala>Val] HGVS Name: HBB:c.41C>T
Hb Name: Hb Yulin Protein Info: β 13(A10) Ala>Val

Protein sequence:

Also known as:

Comments: First discovered by target next-generation sequencing with 0.000045 of frequency in 22260 samples (South China origin). In a recent report, was found in a female during routine thalassemia screening. Hb variant was not detected with the common methods of HPLC and CE but with MALDI-TOF and mass spectrometry.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
