Summary

Floriot et al. (2021) "A total of 106 affected animals were reported to the French National Observatory for Bovine Abnormalities (ONAB, https://www.onab.fr/, Grohs et al. 2016). The first case reported to the ONAB was a cow born in 2008. At birth, the affected animals, which are otherwise healthy, present a dilution of the pigmented, normally red, areas of the coat .... To search for the causative genetic factors responsible for this genetic condition, a genome-wide homozygosity scan followed by whole-genome sequence data analysis was performed."

Molecular Genetics

Floriot et al. (2021): "Analysis of whole-genome sequence data generated from milca animals identified a strong candidate variant within the coding region of the Frizzled-7 gene (FZD7). This gene encodes for a G-protein coupled receptor for Wnt signaling proteins. The variant induces a glycine to alanine substitution in the second extracellular loop, p.(Gly414Ala)."
