Methods: In this study, we examined the mRNA expression of ENPP1 as a candidate gene in heart, liver, spleen, lungs, and kidneys at 3 days and 6 months of age by real-time polymerase chain reaction method and single-nucleotide polymorphism (SNP) loci in 165 Xiangsu pigs by Sanger sequencing. Results: The expression of ENPP1 in different tissues of Xiangsu pigs at different stages was significantly different, and it had high conservation in different species.. Sequence alignment with reference data identified five SNP sites: g.64275T\u2192C and g.64429G\u2192A in intron 19, g.64850T\u2192C and g.64911G\u2192A in intron 20, and g.64527T\u2192C in exon 20. Association analysis revealed that g.64275T\u2192C, g.64429G\u2192A, and g.64527T\u2192C significantly influence the growth performance of Xiangsu pigs (p &lt; 0.05). Conclusions: These findings suggest that ENPP1 polymorphisms are closely associated with growth traits in Xiangsu pigs and may provide valuable insights for molecular breeding of this breed.<\/jats:p>","DOI":"10.3390\/genes16040395","type":"journal-article","created":{"date-parts":[[2025,3,31]],"date-time":"2025-03-31T05:10:07Z","timestamp":1743397807000},"page":"395","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Association Analysis of ENPP1 Tissue Expression, Polymorphism, and Growth Traits in Xiangsu Pigs"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5447-6720","authenticated-orcid":false,"given":"Jiaqi","family":"Chen","sequence":"first","affiliation":[{"name":"Key Laboratory of Animal Genetics, Breeding and Reproduction in the Plateau Mountainous Region, Ministry of Education, Guizhou University, Guiyang 550025, China"},{"name":"College of Animal Science, Guizhou University, Guiyang 550025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiajin","family":"Huang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Animal Genetics, Breeding and Reproduction in the Plateau Mountainous Region, Ministry of Education, Guizhou University, Guiyang 550025, China"},{"name":"College of Animal Science, Guizhou University, Guiyang 550025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4696-5671","authenticated-orcid":false,"given":"Houqiang","family":"Xu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Animal Genetics, Breeding and Reproduction in the Plateau Mountainous Region, Ministry of Education, Guizhou University, Guiyang 550025, China"},{"name":"College of Animal Science, Guizhou University, Guiyang 550025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Yuan, H., Wei, W., Zhang, Y., Li, C., Zhao, S., Chao, Z., Xia, C., Quan, J., and Gao, C.
