Also known as:

Comments: Variant was found in a Kurdish family. Three siblings were carriers, whereas the father and one sibling had no mutations in the β-globin gene. No maternal information was provided. All carriers presented with low haematological indices and abnormal HbA2 (around 5%). Bioinformatics analysis showed that this variant may influence normal splicing process.
