title: Haemoglobin Noah Mehmet Oeztuerk (alpha(2) delta(2)143 (H21)His-->Tyr: A novel delta-chain variant in the 2,3-DPG binding site.
abstract: A new delta-chain variant, delta143 (H21) His-->Tyr or Hb Noah Mehmet Oeztuerk, was discovered during the investigation of the cause of hemolytic anaemia in a 6-month-old infant of Turkish descent. It was detected by Cation exchange high-performance liquid chromatography (CE-HPLC) using PolyCAT A column. P(50) was 20.6+/-0.60 mmHg and 29.3+/-0.40 mmHg for the carrier and the wild-type, respectively. This suggests an increase in oxygen affinity. On routine CE-HPLC Hb A(2) was low (1.2%) and the variant was not detected. An extended family study revealed that the variant was not associated with the anaemia or with any other clinical abnormality.
