The reference allele is (T) for rs41464951, a SNP in the HBA2 gene on chromosome 16, and all three missense alternatives are known, leading to c.427T>A, c.427T>Cand c.427T>G, with three similar consequences:

  • c.427T>A (p.Ter143Lys) is known as Hemoglobin Icaria and can lead to the subtype of alpha thalassemia known as Hemoglobin H disease
  • c.427T>C (p.Ter143Gln) is known as Hemoglobin Constant Spring and may also lead to Hemoglobin H disease
  • c.427T>G (p.Ter143Glu) is known as Hemoglobin Seal Rock and may also lead to Hemoglobin H disease
