Phenotypes

Gutiérrez-Gil et al. (2007): c.64G>A Jolly et al. (2008): c.50_52delTTC Laible et al. (2021): "To better adapt dairy cattle to rapidly warming climates, we aimed to lighten their coat color by genome editing. ... Using gRNA/Cas9-mediated editing, we introduced a three bp deletion in the pre-melanosomal protein 17 gene (PMEL) proposed as causative variant for the semi-dominant color dilution phenotype observed in Galloway and Highland cattl...

Knaust et al. (2016) reported: "evidence that the RTS phenotype results from an epistatic interaction between three independent loci: dilution (that corresponds to the PMEL gene at 55 Mb on BTA5), extension (that corresponds to the MC1R gene on BTA18) and the RTS locus that is located in the interval between 14 and 22 Mb on BTA5. The prerequisites for expression of the RTS phenotype are a eumelanic background due to the presence of the dominan...
