Abstract
Insulin-like growth factor 2 mRNA-binding protein 2 (IGF2BP2, also called IMP2) plays an essential role in the development and maturation of germ cells and embryos and is a candidate gene for goat litter size, based on a previous genome-wide selective sweep analysis. In this study, the mRNA expression level of IGF2BP2 was found to be significantly higher in a single-lamb group than in a multi-lamb group. Insertions/deletions (indels) within the goat IGF2BP2 gene, including P4-Ins-13bp and P5-Del-12bp, were verified in 918 Shaanbei White Cashmere (SBWC) female goats. The minor allelic frequencies (MAFs) of P4-Ins-13bp and P5-Del-12bp loci were 0.349 and 0.295, respectively. Analysis using the Chi-square (χ2) test showed that the genotype (χ2=14.479, P=0.006) distribution of P4-Ins-13bp was significantly different between the single-lamb and multi-lamb groups. Correlation analysis demonstrated that P4-Ins-13bp was significantly associated with goat litter size (P=0.022), and individual goats with the homozygous deletion/deletion (DD) genotype produced more litters than other goats. Therefore, considered as a potential molecular marker significantly related to lambing traits, the P4-Ins-13bp mutation of the goat IGF2BP2 gene can be used in goat breeding with practical molecular marker-assisted selection (MAS) to optimize female reproduction and improve economic efficiency in the goat industry.

Abstract
Insulin-like growth factor 2 mRNA binding protein 1 (IGF2BP1) plays positive roles in the growth, proliferation of cells and early embryos development by binding mRNA targets. Recently, it had been shown that some polymorphic loci within IGF2BP1 gene were associated with growth traits in animals, especially in goats. Therefore, it has been hypothesized that some variants within IGF2BP1 gene may be also involved in growth traits of sheep. Nine insertion/deletion (InDel) mutations within IGF2BP1 were identified and three loci were polymorphic. Meanwhile, the association analyses between three InDels and growth traits were carried out in 745 sheep. The results showed that all InDels included 5 bp InDel in downstream region, 9 bp InDel in intron 4 and 15 bp InDel in intron 2 within IGF2BP1 were significantly associated with growth traits (p<.05). Furthermore, at 5 and 9 bp InDel loci, the individuals of heterozygous genotype (ID) had superior growing performance especially at body weight (BW). In all, three InDels were crucial variants correlated with growth traits and could be applied in marker-assisted selection (MAS) in sheep.
