Cross-species summary:
More specifically called Glanzmann thrombasthenia.
Molecular basis:
By cloning and sequencing a very likely comparative candidate gene (based on the homologous human disorder), Lipscomb et al. (2000) reported "a 14-base insertion in exon 13 and defective splicing of intron 13 in the alphaIIb gene [ITGA2B]" which "disrupted the fourth alphaIIb calcium-binding domain, caused a shift in the reading frame and resulted in a premature termination codon. Possible consequences of this mutation include decreased alphaIIb mRNA stability and production of truncated alphaIIb protein that lacks the transmembrane and cytoplasmic domains and a large portion of the extracellular domain".
Boudreaux et al. (2001) reported a "single nucleotide change at position G1193 (1100) . . . detected in exon 12 of the gene encoding for platelet GPIIb in 2 affected Otterhounds. . . . This nucleotide change would result in substitution of histidine for aspartic acid at position 398 (367) within the third calcium-binding domain of GPIIb"

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.
