Genome wide Copy Number Variation (CNV) detection in Cinisara cattle breed
2017
Copy Number Variations (CNVs) are classes of polymorphic genomic regions including deletions, duplications and insertions of DNA fragments from at least 0.5 kb up to several Mb. CNV represents an important source of genetic variability that provides genomics structural information complementary to the single nucleotide polymorphism (SNP) data. Some CNVs have been shown to be important in both normal phenotypic variability and disease susceptibility in livestock. Several approaches to identify CNVs including FISH, aCGH, SNP array or NGS, were proposed and among these SNP genotyping is relatively low cost, high-throughput and high coverage method. The aim of this study was to identify the CNV…
Effect of CSN1S1 G allele on some characteristics of milk produced by Cinisara cows
2017
In bovine milk about 37-40% of total casein is represented by s1-casein. The CSN1S1 G allele is characterised by a less efficient protein synthesis (about 40%) compared with the other known alleles because of the insertion, in the 19th exon, of a Long Interspersed Nuclear Element relict responsible for a reduced mRNA stability. The lower proportion of s1-casein in milk is associated with faster formation, higher firmness and greater resistance to compression of the curd. The purpose of this study was to analyse the G allele distribution at the CSN1S1 locus in Cinisara breed and its influence on some milk traits. The Cinisara is a small Sicilian breed for which, recently, recovery and safe…
