In pigs, BSCL2 expression increases during adipocyte differentiation. In the present study, we identified significant gene variants associated with fat deposition (FD)-related processes based on subcutaneous fat tissue RNA-seq data. In the association study, to prove our hypothesis, three Polish pig breeds were included: Z\u0142otnicka White (ZW, n = 72), Polish Landrace (PL, n = 201), and Polish Large White (PLW, n = 169). Based on variant calling analysis and \u03c72 tests, BSCL2 mutations showing significantly different genotype\/allele distribution between high- and low-fat pigs were selected for a comprehensive association study. Four interesting BSCL2 variants (rs346079334, rs341493267, rs330154033, and rs81333153) belonging to downstream and missense mutations were investigated. Our study showed a significant decrease in minor allele frequency for two BSCL2 variants (rs346079334 and rs341493267) in PL pigs in 2020\u20132021. In ZW, BSCL2 mutations significantly affected loin and ham fats, meat redness, and growth performance traits, such as feed conversion and daily feed intake. Similar observations were noted for PLW and PL, where BSCL2 mutations influenced fat depositions and meat traits, such as loin eye area, loin mass and fat, carcass yield, and growth performance traits. Based on the observation in pigs, our study supports the theory that BSCL2 expressed in subcutaneous fat is involved in the FD process.<\/jats:p>","DOI":"10.3390\/ani13040641","type":"journal-article","created":{"date-parts":[[2023,2,13]],"date-time":"2023-02-13T05:25:26Z","timestamp":1676265926000},"page":"641","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["The Effect of BSCL2 Gene on Fat Deposition Traits in Pigs"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4368-9624","authenticated-orcid":false,"given":"Katarzyna","family":"Pi\u00f3rkowska","sequence":"first","affiliation":[{"name":"Department of Animal Molecular Biology, National Research Institute of Animal Production, Krakowska 1, 32-083 Balice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julia","family":"Sroka","sequence":"additional","affiliation":[{"name":"Department of Biotechnology and Horticulture, University of Agricultural in Krak\u00f3w, 29-go Listopada 54, 31-425 Krak\u00f3w, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5690-3634","authenticated-orcid":false,"given":"Kacper","family":"\u017bukowski","sequence":"additional","affiliation":[{"name":"Department of Cattle Breeding, National Research Institute of Animal Production, Krakowska 1, 32-083 Balice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8508-9168","authenticated-orcid":false,"given":"Karolina","family":"Zygmunt","sequence":"additional","affiliation":[{"name":"Department of Animal Molecular Biology, National Research Institute of Animal Production, Krakowska 1, 32-083 Balice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8555-0495","authenticated-orcid":false,"given":"Katarzyna","family":"Ropka-Molik","sequence":"additional","affiliation":[{"name":"Department of Animal Molecular Biology, National Research Institute of Animal Production, Krakowska 1, 32-083 Balice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8221-3461","authenticated-orcid":false,"given":"Miros\u0142aw","family":"Tyra","sequence":"additional","affiliation":[{"name":"Department of Pig Breeding, National Research Institute of Animal Production, Krakowska 1, 32-083 Balice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Roumane, A., McIlroy, G.D., Balci, A., Han, W., Delibegovi\u0107, M., Baldassarre, M., Newsholme, P., and Rochford, J.J.
