Facial dysplasia syndrome
Agerholm et al. (2017): "whole genome sequencing of a case-parent trio revealed two de novo variants perfectly associated with the disease: an intronic SNP in the DMBT1 gene and a single non-synonymous variant in the FGFR2 gene. This FGFR2 missense variant (c.927G>T) affects a gene encoding a member of the fibroblast growth factor receptor family, where amino acid sequence is highly conserved between members and across species. It is predic...

Protoporphyria — bovine erythropoietic protoporphyria
The report of the use of a DNA genotyping test by Healy et al. (1995), citing a personal communication from G.S. Johnson at the University of Missouri, implied that the molecular basis of this disorder within the gene for ferrochelatase had been determined by Dr Johnson. Jenkins et al. (1998) appear to have been the first to publicly report the molecular basis of this disorder. They did so by cloning and sequencing a very likely comparative ca...
Thrombopathia, RASGRP2-related — Simmental hereditary thrombopathy; bleeding disorder;
On the strength of a clear candidate gene in which mutations cause the same disorder in dogs (OMIA 001003-9615), Boudreaux et al. (2007) reported that this disorder in a Simmental calf is due to a missense mutation (c.701T>C) in the CalDAG-GEFI gene which is now called RASGRP2. Jansen et al. (2013) reported that "Sanger sequencing confirmed that all thrombopathic animals are homozygous for the [same] pertinent amino acid exchange (c.701T &g...
