In Mexico, the MetS is a national health problem in adults and children. Environmental and genetic factors condition the MetS. However, studies to elucidate the contribution of genetic factors to MetS in Mexico are scarce. A recent study showed that variant rs9282541 (A-allele) in ATP-binding cassette transporter A1 (<i>ABCA1</i>) was associated with T2D in the Maya population in addition to low levels of high-density lipoprotein cholesterol (HDL-C). Thus, this study aimed to determine whether the genetic variant of <i>ABCA1</i> A-allele (rs9282541, NM_005502.4:c.688C &gt; T, NP_005493.2:p.Arg230Cys) is associated with MetS and its components in Mexican Maya children.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>The study was conducted in 508 children aged 9–13 from the Yucatán Peninsula.

Finally, this study reveals a high prevalence of MetS and suggests that variant rs9282541 of the <i>ABCA1</i> gene plays an important role in the developing risk of MetS in Maya children.</p>\u0000 </section>\u0000 </div>","PeriodicalId":8085,"journal":{"name":"Annals of Human Genetics","volume":"88 4","pages":"279-286"},"PeriodicalIF":1.9,"publicationDate":"2024-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139401562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most patients carry pathogenic variants in one of the <i>NF1</i> alleles; nevertheless, patients with both <i>NF1</i>-mutated copies have been described. Interestingly, all <i>NF1</i> variants carried by the known SNF compound heterozygotes were missense/splicing variants or in-frame insertion-deletions.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Aims</h3>\u0000 \u0000 <p>To investigate whether there is a differential expression of <i>NF1</i> variant alleles in an <i>NF1</i> compound heterozygous SNF patient possibly contributing to clinical phenotype.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Materials &amp; methods</h3>\u0000 \u0000 <p>We performed an allele-specific expression study, by chip-based digital PCR, in an SNF family carrying two <i>NF1</i> missense variants.
