β-lactoglobulin gene promoter: new SNPs in sheep and goat

β-lactoglobulin (β-lg) is the major whey protein in milk of ruminants and several non ruminant species, but it is lacking in rodents, lagomorphs and human. The aim of this work was sequencing the promoter region of β-lg gene in Sicilian sheep and goat dairy breeds, in order to identify polymorphisms. In these species, the promoter region was aligned using the sequences available on database. A common set of primers was designed to amplify and sequence a fragment of approximately 2.1 kb. Within this region, 12 single nucleotide polymorphisms (SNPs) were identified in goat breeds: 7 out of them were not yet reported in literature. Moreover, in sheep breeds 15 SNPs were newly identified. Using…

Erratum: Copy Number Variation and Missense Mutations of the Agouti Signaling Protein (ASIP) Gene in Goat Breeds with Different Coat Colors

In goats, classical genetic studies reported a large number of alleles at the Agouti locus with effects on coat color and pattern distribution. From these early studies, the dominant AWt (white/tan) allele was suggested to cause the white color of the Saanen breed. Here, we sequenced the coding region of the goat ASIP gene in 6 goat breeds (Girgentana, Maltese, Derivata di Siria, Murciano-Granadina, Camosciata delle Alpi, and Saanen), with different coat colors and patterns. Five single nucleotide polymorphisms (SNPs) were identified, 3 of which caused missense mutations in conserved positions of the cysteine-rich carboxy-terminal domain of the protein (p.Ala96Gly, p.Cys126Gly, and p.Val128…
