We collected blood samples from 555 Jewish persons to 1) estimate the heterozygote frequency for NADH MetHb R deficiency; and 2) determine if external variables such as age, gender, and ingested medications may alter the NADH MetHb R activity and thereby alter estimates of heterozygosity. Two persons possibly heterozygous for the deficiency were identified (carrier incidence = 1\/277; calculated homozygote incidence = 1\/309,000 Jewish births). A difference in enzyme activity was found between males and females (P &lt; 0.03). We have examined the influence of the mean red cell age on the activity of erythrocyte NADH MetHb R and found it not to be materially influenced by mean red cell age; thus the possible intersex differences of mean red cell age cannot explain this observation. No significant difference (P &gt; 0.1) was seen between persons ingesting the following drugs and those not: Dilantin; antidepressants\/sedatives; cardiac, antineoplastic, or antigout\/antiinflammatory drugs; thyroid supplements, estrogen\u2010containing preparations, and antihistamines. NADH MetHb R activity did not correlate with age or spontaneous abortion. We conclude that heterozygosity for NADH MetHb R deficiency is not prevalent among Ashkenazic Jewish persons, and that external variables should be considered to ensure accurate interpretation of NADH MetHb R activity for correct estimation of heterozygosity.<\/jats:p>","DOI":"10.1002\/ajh.2830120103","type":"journal-article","created":{"date-parts":[[2007,2,21]],"date-time":"2007-02-21T06:24:10Z","timestamp":1172039050000},"page":"13-18","source":"Crossref","is-referenced-by-count":6,"title":["Studies of nicotinamide adenine dinucleotide methemoglobin reductase activity in a jewish population"],"prefix":"10.1002","volume":"12","author":[{"given":"Michael R.","family":"Moore","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcel E.","family":"Conrad","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"Jr.","given":"Edwin L.","family":"Bradley","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Josef T.","family":"Prchal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,7,11]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/0006-3002(59)90324-5"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(64)80017-2"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM196510142731602"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM196811212792102"},{"key":"e_1_2_1_6_2","first-page":"417","article-title":"DPNH\u2010methemoglobin reductase deficiency and hereditary methemoglobinemia","volume":"8","author":"Jaffe ER","year":"1971","journal-title":"Semin Hematol"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1182\/blood.V13.8.795.795"},{"key":"e_1_2_1_8_2","first-page":"76","volume-title":"Red Cell Metabolism: A Manual of Biochemical Methods","author":"Beutler E","year":"1975"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/0006-291X(67)90529-3"},{"key":"e_1_2_1_10_2","first-page":"67","volume-title":"Principles and Procedures of Statistics","author":"Steel RGD","year":"1960"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(65)91782-4"},{"key":"e_1_2_1_12_2","doi-asserted-by":"crossref","first-page":"87","DOI":"10.1182\/blood.V29.1.87.87","article-title":"Detection of glucose\u20106\u2010phosphate dehydrogenase deficient heterozygotes","volume":"29","author":"Stamatoyannopoulos G","year":"1967","journal-title":"Blood"},{"key":"e_1_2_1_13_2","first-page":"1459","volume-title":"Metabolic Basic of Inherited Disease","author":"Schwartz JM","year":"1978"}],"container-title":["American Journal of Hematology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fajh.2830120103","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ajh.2830120103","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,13]],"date-time":"2023-11-13T01:40:55Z","timestamp":1699839655000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ajh.2830120103"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1982,2]]},"references-count":12,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1982,2]]}},"alternative-id":["10.1002\/ajh.2830120103"],"URL":"https:\/\/doi.org\/10.1002\/ajh.2830120103","archive":["Portico"],"relation":{},"ISSN":["0361-8609","1096-8652"],"issn-type":[{"value":"0361-8609","type":"print"},{"value":"1096-8652","type":"electronic"}],"subject":[],"published":{"date-parts":[[1982,2]]}}}
