METHODS: A total of 200 congenital heart disease patients (100 tetralogy of Fallot patients and 100 ventricular septal defect patients) and 100 congenital heart defect-free controls were recruited, and quantitative real-time PCR analysis was used to replicate the association of two copy number variations with congenital heart defects in a Chinese Han population. RESULTS: One deletion at PRKAB2 and one duplication at PPM1K were found in two of the tetralogy of Fallot patients, respectively; while all these regions were duplicated in both ventricular septal defect patients and in the 100 congenital heart defects-free controls. CONCLUSIONS: We replicated the copy number variations at the disease-candidate genes of PRKAB2 and PPM1K with tetralogy of Fallot in a Chinese Han population, and in patients with ventricular septal defect mutations in these two genes were not found. These results indicate the same molecular population genetics exist in these two genes with different ethnicity. This shows that these two genes are possibly specific pf tetralogy of Fallot candidates.<\/jats:p>","DOI":"10.1590\/1806-9282.65.6.786","type":"journal-article","created":{"date-parts":[[2019,7,20]],"date-time":"2019-07-20T19:07:36Z","timestamp":1563649656000},"page":"786-790","source":"Crossref","is-referenced-by-count":3,"title":["The study of copy number variations in the regions of PRKAB2 and PPM1K among congenital heart defects patients"],"prefix":"10.1590","volume":"65","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1998-724X","authenticated-orcid":false,"given":"Han-Quan","family":"Dong","sequence":"first","affiliation":[{"name":"Tianjin Children's Hospital, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9481-3050","authenticated-orcid":false,"given":"Yue-Xin","family":"Du","sequence":"additional","affiliation":[{"name":"Tianjin Municipal Women and Children health care center, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","published-online":{"date-parts":[[2019,6]]},"reference":[{"issue":"2","key":"ref1","doi-asserted-by":"crossref","first-page":"85","DOI":"10.1038\/nrg1767","article-title":"Structural variation in the human genome","volume":"7","author":"Feuk L","year":"2006","journal-title":"Nat Rev Genet"},{"issue":"7118","key":"ref2","doi-asserted-by":"crossref","first-page":"444","DOI":"10.1038\/nature05329","article-title":"Global variation in copy number in the human genome","volume":"444","author":"Redon R","year":"2006","journal-title":"Nature"},{"issue":"1","key":"ref3","doi-asserted-by":"crossref","first-page":"31","DOI":"10.1093\/oxfordjournals.aje.a113979","article-title":"Congenital heart disease: prevalence at livebirth.
