IthaID: 2569

Names and Sequences

Functionality: Disease modifying mutation
Common Name: Triplicated α (anti-4.2) HGVS Name: N/A

Also known as:

Comments: Leftward 4.2 kb deletion caused by reciprocal recombination between X boxes producing a chromosome with only one functional α-gene (α-4.2 or leftward deletion) causing α-thalassaemia and this α-triplication allele (anti-4.2) without a thalassaemic effect.
