IthaID: 2303

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: Variant of Uncertain Significance
Common Name: CD 100 CTC>TTC (Leu>Phe) HGVS Name: HBA1:c.301C>T
Hb Name: Hb Weesp Protein Info: α1 100 Leu>Phe

Protein sequence:

Also known as:

Comments: The substitution of the hydrophobic amino acid leucine by the bulkier phenylalanine on the α1-globin chain of Hb Weesp does not result in major changes in expression or functionality. No clinical consequences.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
