For subsequent analysis, capture sequencing targeting highly heterozygotic single nucleotide polymorphism sites was conducted. Paternal\u2010specific alleles were used to calculate the total and individual fetal fractions and determine zygosity. A two\u2010step Bayes Factor model was applied to clarify the complex genomic landscape in the maternal plasma: the first step involved determining whether the twins inherited the same haplotype, and the second step involved estimating their individual genotypes. NIPT results were subsequently confirmed by invasive diagnosis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Nine twin pregnancies were recruited, including five DZ and four monozygotic (MZ) twins. The earliest gestational age was 8<jats:sup>+0<\/jats:sup> weeks, and the minimum fetal fraction was 4.6%. Three twin pregnancies were reported with one affected fetus, while the remaining six were reported without affected fetuses. Two dichorionic diamniotic twin pregnancies were confirmed to be MZ twins. The NIPT results were 100% consistent with those of invasive procedures or diagnostic genetic testing after birth.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study is the first to perform NIPT for single\u2010gene disorders in twin pregnancies and preliminarily confirm its clinical feasibility. Acknowledging the twins' genotypes in the first trimester is valuable as it empowers obstetric care providers and parents to have adequate time for pregnancy management and decision\u2010making.<\/jats:p><\/jats:sec>","DOI":"10.1002\/pd.6565","type":"journal-article","created":{"date-parts":[[2024,4,22]],"date-time":"2024-04-22T12:14:50Z","timestamp":1713788090000},"page":"1015-1023","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Noninvasive twin genotyping for recessive monogenic disorders by relative haplotype dosage"],"prefix":"10.1002","volume":"44","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6432-1100","authenticated-orcid":false,"given":"Lingrong","family":"Kong","sequence":"first","affiliation":[{"name":"Department of Fetal Medicine &amp; Prenatal Diagnosis Center Shanghai Key Laboratory of Maternal Fetal Medicine Shanghai Institute of Maternal\u2010Fetal Medicine and Gynecologic Oncology Shanghai First Maternity and Infant Hospital School of Medicine Tongji University  Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhenhua","family":"Zhao","sequence":"additional","affiliation":[{"name":"Genetic and Prenatal Diagnosis Center Department of Obstetrics and Gynecology The First Affiliated Hospital of Zhengzhou University  Zhengzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xinyu","family":"Fu","sequence":"additional","affiliation":[{"name":"Genetic and Prenatal Diagnosis Center Department of Obstetrics and Gynecology The First Affiliated Hospital of Zhengzhou University  Zhengzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huanyun","family":"Li","sequence":"additional","affiliation":[{"name":"Genetic and Prenatal Diagnosis Center Department of Obstetrics and Gynecology The First Affiliated Hospital of Zhengzhou University  Zhengzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingqi","family":"Zhu","sequence":"additional","affiliation":[{"name":"Genetic and Prenatal Diagnosis Center Department of Obstetrics and Gynecology The First Affiliated Hospital of Zhengzhou University  Zhengzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Di","family":"Wu","sequence":"additional","affiliation":[{"name":"Celula (China) Medical Technology Co., Ltd.
