Compared with 16p11.2 deletion variants, duplication variants have lower penetrance and higher phenotypic heterogeneity. Due to limited perinatal data, early phenotypes warrant further investigation. We report the case of a neonate with seizures, microcephaly, and neurodevelopmental delay whose parents were phenotypically normal. Whole-exome sequencing revealed a 200.15-kb duplication in 16p11.2 seq[GRCh38]dup(16)(p11.2-p11.2) (chr16:29,963,728-30,168,686) in the proband and his mother, which was confirmed via quantitative polymerase chain reaction. This case highlights the potential link between 16p11.2 duplications and neonatal neurodevelopmental disorders, emphasizing the need for genetic counseling in affected families.<\/jats:p>","DOI":"10.1177\/03000605251358613","type":"journal-article","created":{"date-parts":[[2025,7,24]],"date-time":"2025-07-24T09:43:32Z","timestamp":1753350212000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Neonatal seizures associated with a rare familial 16p11.2 microduplication: A case report"],"prefix":"10.1177","volume":"53","author":[{"given":"Jun","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Neonatology, Anhui Provincial Children\u2019s Hospital\/Children\u2019s Hospital of Fudan University (Affiliated Anhui Branch), China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shaohua","family":"Bi","sequence":"additional","affiliation":[{"name":"Department of Neonatology, Anhui Provincial Children\u2019s Hospital\/Children\u2019s Hospital of Fudan University (Affiliated Anhui Branch), China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Neonatology, Anhui Provincial Children\u2019s Hospital\/Children\u2019s Hospital of Fudan University (Affiliated Anhui Branch), China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-4212-6773","authenticated-orcid":false,"given":"Liying","family":"Dai","sequence":"additional","affiliation":[{"name":"Department of Neonatology, Anhui Provincial Children\u2019s Hospital\/Children\u2019s Hospital of Fudan University (Affiliated Anhui Branch), China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,7,24]]},"reference":[{"key":"e_1_3_7_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41431-024-01601-2"},{"key":"e_1_3_7_3_2","doi-asserted-by":"publisher","DOI":"10.3390\/genes15081053"},{"key":"e_1_3_7_4_2","doi-asserted-by":"publisher","DOI":"10.1038\/nrg2593"},{"key":"e_1_3_7_5_2","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.2009.069369"},{"key":"e_1_3_7_6_2","doi-asserted-by":"publisher","DOI":"10.1212\/NXG.0000000000200018"},{"key":"e_1_3_7_7_2","doi-asserted-by":"publisher","DOI":"10.1038\/mp.2016.84"},{"key":"e_1_3_7_8_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature10406"},{"key":"e_1_3_7_9_2","doi-asserted-by":"publisher","DOI":"10.1111\/head.12246"},{"key":"e_1_3_7_10_2","doi-asserted-by":"publisher","DOI":"10.1038\/gim.2015.30"},{"key":"e_1_3_7_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajhg.2024.08.015"},{"key":"e_1_3_7_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroimage.2019.116155"},{"key":"e_1_3_7_13_2","doi-asserted-by":"publisher","DOI":"10.1136\/jmedgenet-2012-101203"},{"key":"e_1_3_7_14_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature08689"},{"key":"e_1_3_7_15_2","volume-title":"GeneReviews\u00ae [Internet]","author":"Yang K","year":"2018","unstructured":"Yang K, Quiroz V, Ebrahimi-Fakhari D.
