Haemoglobin variants and ABO blood group polymorphisms were associated with asymptomatic malaria, with HbAA showing significantly higher odds of infection. Although higher odds were observed among individuals with O Rh D\u2013positive, O\/HbAA, and B\/HbAS phenotypes, these associations were not statistically significant. These findings highlight the complex role of host genetic factors in asymptomatic malaria carriage and underscore the need for further studies with larger sample sizes to clarify these associations.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/hsr2.72275","type":"journal-article","created":{"date-parts":[[2026,4,3]],"date-time":"2026-04-03T04:51:15Z","timestamp":1775191875000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Role of Haemoglobin Variants and Red Blood Cell Polymorphisms in Asymptomatic Malaria: A Cross\u2010Sectional Study"],"prefix":"10.1002","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6489-167X","authenticated-orcid":false,"given":"Enoch","family":"Aninagyei","sequence":"first","affiliation":[{"name":"Department of Biomedical Sciences, School of Basic and Biomedical Sciences University of Health and Allied Sciences Ho Volta Region Ghana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Comfort Addo","family":"Boatey","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences, School of Basic and Biomedical Sciences University of Health and Allied Sciences Ho Volta Region Ghana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4787-9473","authenticated-orcid":false,"given":"John Gameli","family":"Deku","sequence":"additional","affiliation":[{"name":"Department of Medical Laboratory Sciences, School of Allied Health Sciences University of Health and Allied Sciences Ho Volta Region Ghana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9620-6374","authenticated-orcid":false,"given":"Adjoa Agyemang","family":"Boakye","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences, School of Basic and Biomedical Sciences University of Health and Allied Sciences Ho Volta Region Ghana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ebenezer","family":"Nyarkotey","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences, School of Basic and Biomedical Sciences University of Health and Allied Sciences Ho Volta Region Ghana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gifty","family":"Larbi","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences, School of Allied Health Sciences University of Cape Coast Cape Coast Central Region Ghana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Desmond Omane","family":"Acheampong","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences, School of Allied Health Sciences University of Cape Coast Cape Coast Central Region Ghana"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,4,2]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pbio.1002380"},{"key":"e_1_2_13_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-3156.2004.01277.x"},{"key":"e_1_2_13_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/ng.554"},{"key":"e_1_2_13_5_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0011358"},{"key":"e_1_2_13_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1473-3099(12)70055-5"},{"key":"e_1_2_13_7_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13104-019-4181-8"},{"key":"e_1_2_13_8_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature03631"},{"key":"e_1_2_13_9_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0711401105"},{"key":"e_1_2_13_10_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12936-024-05081-z"},{"key":"e_1_2_13_11_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12936-024-04886-2"},{"key":"e_1_2_13_12_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0705390104"},{"key":"e_1_2_13_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.parepi.2024.e00378"},{"key":"e_1_2_13_14_1","doi-asserted-by":"publisher","DOI":"10.1017\/S095026882200005X"},{"key":"e_1_2_13_15_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12879-023-08134-x"},{"key":"e_1_2_13_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1286-4579(03)00162-X"},{"key":"e_1_2_13_17_1","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2002-10-3105"},{"key":"e_1_2_13_18_1","doi-asserted-by":"publisher","DOI":"10.1186\/1475-2875-8-16"},{"key":"e_1_2_13_19_1","doi-asserted-by":"publisher","DOI":"10.1155\/2016\/5368793"},{"key":"e_1_2_13_20_1","doi-asserted-by":"publisher","DOI":"10.3923\/RJMSCI.2012.247.250"},{"key":"e_1_2_13_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/S2221-1691(11)60045-2"},{"key":"e_1_2_13_22_1","unstructured":"V.
