IthaID: 2550

Names and Sequences

Functionality: Neutral polymorphism Pathogenicity: N/A
Common Name: African I duplication HGVS Name: NC_000011.10: g.5372677_5372678insCACCTCCACTTdup5226885_5372677

Also known as:

Comments: The variant was present in conjunction with the a3.7 Kb deletion (ithaID: 300) and the HbS mutation (ithaID: 824). The phenotype associated with this genetic variant is likely to be silent (normal haematology) when not present with other haemoglobinopathy mutations.
