Genotype tests for &lt;i&gt;NAT1&lt;\/i&gt; alleles &lt;i&gt;*4, *10&lt;\/i&gt; and &lt;i&gt;*11,&lt;\/i&gt; and &lt;i&gt;NAT2&lt;\/i&gt; alleles &lt;i&gt;*4, *5, *6A&lt;\/i&gt; and &lt;i&gt;*7A,&lt;\/i&gt; using PCR-RFLP analysis, were performed in 172 healthy Portuguese individuals and 88 patients with squamous cell carcinoma of the larynx. &lt;i&gt;NAT1&lt;\/i&gt; and &lt;i&gt;NAT2&lt;\/i&gt; genotype frequencies were correlated between patients and control groups, using the chi-square test. Odds ratios and 95% confidence intervals were calculated from 2 \u00d7 2 tables with the Fisher\u2019s exact model. The statistical analysis of &lt;i&gt;NAT1&lt;\/i&gt; and &lt;i&gt;NAT2&lt;\/i&gt; genotype frequencies revealed a significant difference of &lt;i&gt;NAT1*10\/*11&lt;\/i&gt; (p = 0.038) and &lt;i&gt;NAT2*5\/*7&lt;\/i&gt; (p = 0.003) genotype distribution between cases and controls. We also observed differences concerning tumor location, since &lt;i&gt;NAT1*10\/*11&lt;\/i&gt; genotype frequency was significantly different when comparing normal control individuals with the glottic subgroup of patients. The present data suggest that &lt;i&gt;NAT1&lt;\/i&gt; and &lt;i&gt;NAT2&lt;\/i&gt; polymorphisms may be correlated with an increased risk of larynx cancer.<\/jats:p>","DOI":"10.1159\/000058026","type":"journal-article","created":{"date-parts":[[2003,4,15]],"date-time":"2003-04-15T21:05:17Z","timestamp":1050440717000},"page":"206-212","source":"Crossref","is-referenced-by-count":16,"title":["Polymorphisms of Arylamine N-Acetyltransferase (NAT1 and NAT2) and Larynx Cancer Susceptibility"],"prefix":"10.1159","volume":"64","author":[{"given":"Gra\u00e7a","family":"Varzim","sequence":"first","affiliation":[]},{"given":"Eurico","family":"Monteiro","sequence":"additional","affiliation":[]},{"given":"Regina","family":"Silva","sequence":"additional","affiliation":[]},{"given":"Carlos","family":"Pinheiro","sequence":"additional","affiliation":[]},{"given":"Carlos","family":"Lopes","sequence":"additional","affiliation":[]}],"member":"127","published-online":{"date-parts":[[2002,5,24]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1006\/abbi.1993.1116"}],"container-title":["ORL"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/58026","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/58026","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T03:57:47Z","timestamp":1745467067000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000058026"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2002]]},"references-count":1,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2002,6,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000058026","archive":["Portico"],"relation":{},"ISSN":["0301-1569","1423-0275"],"issn-type":[{"value":"0301-1569","type":"print"},{"value":"1423-0275","type":"electronic"}],"subject":[],"published":{"date-parts":[[2002]]}}}
