Also known as: Hb White Rose

Comments: Found in a 75-year-old French Caucasian male suffering from Waldenstrom disease presented with Hb 10 g/dL, MCV 94 fL, MCH 32.3 pg. HPLC analysis shown normal levels of Hb A2 2.5 %, Hb F 0.5 % and an abnormal peak of 14.5 %. Hb White Rose is the corresponding HBA1 or HBA2 variant (first report).

We follow the HGVS sequence variant nomenclature and IUPAC standards.
