Also known as: Hb Lakeview Terrace
Comments: Co-inherited with SEA deletion, red cell indices are consistent with this finding. HPLC findings, appears as shoulder of Hb A peak (Primus Resolution). Recently, the variant reported in compound heterozygosity with Hb D-Los Angeles [IthaID: 1217] in a 11-month old infant presented with Hb 12.1 g/dL, MCH 24.1 pg, MCHC 33.8 g/dL, MCV 71.3 fL and RBC 5.02 10^12/L.
We follow the HGVS sequence variant nomenclature and IUPAC standards.
