Species-specific name: Simmental hereditary thrombopathy; bleeding disorder;
History: Simmental hereditary thrombopathy was previously listed as OMIA 001003-9913 : Thrombopathia in Bos taurus
Mapping: In a GWAS involving 6 affected and 43 normal Fleckvieh (each genotyped with the Illumina BovineHD SNP Chip, yielding 652,856 informative SNPs), Jansen et al. (2013) mapped this disorder in Fleckvieh to chromosome BTA29. Subsequent autozygosity mapping narrowed the region to a 6.3Mb interval that contains the RASGRP2 gene.
Molecular basis: 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 > C, p.L234P, Chr29:43599204" (UMD3.1 reference coordinates). Aebi et al. (2016) reported the same causal mutation in affected Simmental cattle in Switzerland.
Prevalence: In a project involving the whole-genome sequencing (WGS) of 43 Fleckvieh cattle with average coverage 7.46X (range 4.17X to 24.98X), Jansen et al. (2013) reported that 8/43 carried the c.701T>C mutation, giving a gene frequency of 9% in this breed. Aebi et al. (2016) reported "A frequency of 10% carriers for the associated mutation was detected in a sample of 145 Simmental sires which were used 2013 for artificial insemination in Switzerland."

Variants
By default, variants are sorted chronologically by year of publication, to provide a historical perspective.
Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending
order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column
headers.
WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
