Semen samples were assessed according to the WHO 2010 Laboratory Manual and compared with 31 fertile controls. We focused our genetic analysis on the exons of the main globozoospermia-associated genes, performing qualitative PCR to assess deletion of DPY19L2 and sequencing to detect mutations of SPATA16 and PICK1. SDF was evaluated using the TUNEL assay. In Group G, 10 patients had a complete form of globozoospermia, whereas 8 patients had a partial form. Molecular analysis revealed deletion of DPY19L2 in six of the patients, all of them with complete globozoospermia, while no mutations were found in the examined exons of PICK1 and SPATA16. TUNEL analysis showed a higher SDF% in Group G. Our findings confirm DPY19L2 defects as the most frequent genetic alteration in Italian patients contributing to globozoospermic phenotypes. Furthermore, spermatozoa with acrosomal defects could also display high levels of SDF as a possible consequence of abnormally remodeled chromatin. The possible effect on offspring of chromatin structure abnormalities and altered DNA integrity should be carefully evaluated by clinicians, especially regarding the feasibility and safety of artificial reproductive techniques, which represent the only treatment that allows these patients to conceive.<\/jats:p>","DOI":"10.3390\/life11070641","type":"journal-article","created":{"date-parts":[[2021,7,1]],"date-time":"2021-07-01T02:44:39Z","timestamp":1625107479000},"page":"641","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Molecular Analysis of DPY19L2, PICK1 and SPATA16 in Italian Unrelated Globozoospermic Men"],"prefix":"10.3390","volume":"11","author":[{"given":"Fabiana","family":"Faja","sequence":"first","affiliation":[{"name":"Laboratory of Seminology\u2014\u201cLoredana Gandini\u201d Sperm Bank, Department of Experimental Medicine, \u201cSapienza\u201d University of Rome, Viale del Policlinico 155, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6042-6474","authenticated-orcid":false,"given":"Francesco","family":"Pallotti","sequence":"additional","affiliation":[{"name":"Laboratory of Seminology\u2014\u201cLoredana Gandini\u201d Sperm Bank, Department of Experimental Medicine, \u201cSapienza\u201d University of Rome, Viale del Policlinico 155, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8333-6295","authenticated-orcid":false,"given":"Francesco","family":"Cargnelutti","sequence":"additional","affiliation":[{"name":"Laboratory of Seminology\u2014\u201cLoredana Gandini\u201d Sperm Bank, Department of Experimental Medicine, \u201cSapienza\u201d University of Rome, Viale del Policlinico 155, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4666-0971","authenticated-orcid":false,"given":"Giulia","family":"Senofonte","sequence":"additional","affiliation":[{"name":"Laboratory of Seminology\u2014\u201cLoredana Gandini\u201d Sperm Bank, Department of Experimental Medicine, \u201cSapienza\u201d University of Rome, Viale del Policlinico 155, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tania","family":"Carlini","sequence":"additional","affiliation":[{"name":"Laboratory of Seminology\u2014\u201cLoredana Gandini\u201d Sperm Bank, Department of Experimental Medicine, \u201cSapienza\u201d University of Rome, Viale del Policlinico 155, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Lenzi","sequence":"additional","affiliation":[{"name":"Laboratory of Seminology\u2014\u201cLoredana Gandini\u201d Sperm Bank, Department of Experimental Medicine, \u201cSapienza\u201d University of Rome, Viale del Policlinico 155, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesco","family":"Lombardo","sequence":"additional","affiliation":[{"name":"Laboratory of Seminology\u2014\u201cLoredana Gandini\u201d Sperm Bank, Department of Experimental Medicine, \u201cSapienza\u201d University of Rome, Viale del Policlinico 155, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donatella","family":"Paoli","sequence":"additional","affiliation":[{"name":"Laboratory of Seminology\u2014\u201cLoredana Gandini\u201d Sperm Bank, Department of Experimental Medicine, \u201cSapienza\u201d University of Rome, Viale del Policlinico 155, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"185","DOI":"10.1007\/s40618-017-0713-z","article-title":"Varicocele and semen quality: A retrospective case-control study of 4230 patients from a single centre","volume":"41","author":"Pallotti","year":"2018","journal-title":"J.
