Identification of ANAPC13 gene polymorphisms associated with body measurement traits in Bos taurus

Abstract

ABSTRACT. Body measurement traits, influenced by genes and environmental factors, play numerous important roles in the value assessment of productivity and economy. There has been some indication that ANAPC13 influences adult height. We used PCR-SSCP and DNA sequencing technology to identify polymorphisms in the ANAPC13 gene. A polymorphism in intron 1 (A > G at base 17) was identified and an additional polymorphic site (C > T at base 42) was also uncovered, which accompanied the previous polymorphism in more than 98% of the subjects. The two novel polymorphisms in exon 1 were assayed and potential associations with body measurement traits were evaluated in 404 individuals. Three genotypes were detected in the study group, named AACC, AGCT and GGTT. Significant differences were observed between genotypes AACC and AGCT for body length, withers height, hip height, hip width, heart girth, pin bone width. However, no associations were found among any genotypes and chest depth. We conclude that polymorphisms and mutations in non-coding regions of the ANAPC13 ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 11 (3): 2862-2870 (2012) ANAPC13 gene associated with body traits in Bos taurus 2863 gene significantly affect body measurement traits.

Imputation of canine genotype array data using 365 whole-genome sequences improves power of genome-wide association studies

“…With the imputation panel, we saw a refinement in several QTL regions–for example, the chromosome 3 association near the genes LCORL and ANAPC13 , both of which have previously been associated with body size [5,16,36,37,39]. Using imputed data, this QTL had a more significant and defined association, compared to the CanineHD array data alone (S2A Fig).…”

Genetic improvement of economic traits in Murrah buffalo using significant SNPs from genome-wide association study

“…In growth traits ANAPC13 gene present on ± 20kb window of SNP in 1st chromosome have in uence in adult height, stature morphogenesis and growth of the skeleton. It could be an attractive candidate gene for body measurement traits in Bos Taurus(Jiang et al, 2012). LHX2 gene on 12th chromosome have signi cant expression support for maintaining distal posterior SHH gene expression during progressive limb outgrowth and development(Watson et al, 2018).…”
