| Popis: | The BMPRIB gene is one of the main genes that can be used as a molecular genetic marker for the early selection of highly productive ewes. It is well-documented that the p.Q249R (g.746A > G) is the first mutation in the kinase domain of the BMPR1B gene that is highly related to increased ovulation rate and litter size. It is likely that the presence of the p.Q249R mutation in the sheep population is one of the factors contributing to the outstanding productivity of the sheep. Moreover, in recent years, researchers have been explored other polymorphisms in the BMPR1B gene with respect to reproductive traits in sheep. Therefore, we carried out the current study to evaluate the association between polymorphisms in this gene and sheep litter size from all appropriate studies. As a result, among 41 polymorphisms in the ovine BMPRIB gene, eight variants, including p.Q249R (g.746A > G), g.29362047T > C, g.29427689G > A, BMPR1B-2 (ss:1960972599), g.29382337G > A, g.29382340G > A, rs1092293287 (10 bp insertion/deletion) and g.29380965A > G were found to be associated with litter size in sheep. This systematic analysis presents the most current data evidence for BMPRIB polymorphisms, highlighting the need for further large-scale studies to determine more important variants. |
