A fast-moving, anodal band, identified as Hb Bart\u2019s, was found in 7 (l,6%) of the specimens, this being the lowest incidence of the variant yet found in an indigenous African population. The levels of Hb Bart\u2019s ranged from 1.3 to 5.5% of the haemoglobin. These findings were confirmed by alkaline-starch gel electrophoresis and at the same time absence of the slow-moving haemoglobin, Hb Constant Spring was established. Subsequent follow-up of 4 of the infants at 4 months of postnatal life showed that the abnormal component had disappeared. The babies with Hb Bart\u2019s had a marked microcytosis and low mean corpuscular haemoglobin levels whilst their parents showed no haematological or electrophoretic signs of &lt;sub&gt;\u03b1&lt;\/sub&gt;-thalassaemia. The significance of these findings is discussed in the light of previously reported studies on various Negro groups.<\/jats:p>","DOI":"10.1159\/000207623","type":"journal-article","created":{"date-parts":[[2009,3,4]],"date-time":"2009-03-04T06:05:48Z","timestamp":1236146748000},"page":"33-38","source":"Crossref","is-referenced-by-count":4,"title":["Hb Bart\u2019s and its Significance in the South African Negro"],"prefix":"10.1159","author":[{"given":"T.S.","family":"Piliszek","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,3,3]]},"container-title":["Acta Haematologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/207623","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000207623","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T12:38:05Z","timestamp":1777466285000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000207623"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,3,3]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000207623","archive":["Portico"],"relation":{},"ISSN":["0001-5792","1421-9662"],"issn-type":[{"value":"0001-5792","type":"print"},{"value":"1421-9662","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,3,3]]}}}
