The Rhesus D negative phenotype has a high molecular diversity. We report a rare case of serological D negative with existence of complete RHD gene in a 43-year-old Omani male blood donor. Molecular analysis of RHD exons showed duplication across the boundary of intron 3 and exon 4. This is a 37 bp insert in RHD exon 4 along with c.609 G&gt;A mutation. We are uncertain if the presence of RHD\u03a8 is homozygous (RHD\u03a8\/RHD\u03a8) or hemizygous (RHD\u03a8\/del). Therefore, molecular basis of D zygosity determination would be a good approach to further explore the case.<\/jats:p>","DOI":"10.5001\/omj.2023.11","type":"journal-article","created":{"date-parts":[[2021,10,18]],"date-time":"2021-10-18T13:53:14Z","timestamp":1634565194000},"page":"e488-e488","source":"Crossref","is-referenced-by-count":1,"title":["RHD Positive Haplotype in D Negative Omani Blood Donor"],"prefix":"10.5001","volume":"38","member":"2907","published-online":{"date-parts":[[2023,3,31]]},"container-title":["Oman Medical Journal"],"original-title":[],"deposited":{"date-parts":[[2023,4,26]],"date-time":"2023-04-26T03:27:43Z","timestamp":1682479663000},"score":1,"resource":{"primary":{"URL":"https:\/\/omjournal.org\/articleDetails.aspx?coType=1&aId=3370"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,3,31]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2023,3,31]]}},"URL":"https:\/\/doi.org\/10.5001\/omj.2023.11","relation":{},"ISSN":["1999-768X","2070-5204"],"issn-type":[{"value":"1999-768X","type":"print"},{"value":"2070-5204","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,3,31]]}}}
