The  Period circadian regulator  ( PER ) gene family, including  PER1 ,  PER2  and  PER3 , codes transcriptional repressors which could accurately control biological rhythms.  PER1/2  gene was proved to be associated with bone mass and  PER1  gene was associated with insulin-like growth factor binding proteins 3 (IGFBP3) levels in serum. However, it was few studies reported genetic effects of  PER  gene on growth traits at the individual level. In this study, we identified the potential insertion/deletion (indel) loci in  PER1/2/3  gene, and then explored the relationship between goat growth traits and the frequency of genotype in Shaanbei white cashmere goats ( n  = 827). As a result, a 9 bp indel within  PER1  gene (g.27528003-27528011 del.TGCTGCTGC; rs642467689) was identified using molecular biology techniques. In addition, there existed significant correlation between the 9 bp indel and body height, height at hip cross, chest depth, body length index and cannon circumference index of goats. These results suggested that the 9 bp indel variation in  PER1  gene was associated with goat growth traits, providing the theoretical basic for the role of  PER1  gene in goat breeding.

An upstream deletion polymorphism within the goat Period circadian regulator 1 ( PER1 ) gene was associated with growth traits
