Genes affected

TBXA2R (HGNC:11608): (thromboxane A2 receptor) This gene encodes a member of the G protein-coupled receptor family. The protein interacts with thromboxane A2 to induce platelet aggregation and regulate hemostasis. A mutation in this gene results in a bleeding disorder. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2009]

Variant summary: TBXA2R c.*841A>G is located in the untranslated mRNA region downstream of the termination codon. The variant allele was found at a frequency of 6.2e-05 in 144146 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.*841A>G in individuals affected with Bleeding Diathesis Due To Thromboxane Synthesis Deficiency and no experimental evidence demonstrating its impact on protein function have been reported. This variant is also observed as c.1213A>G (p.Arg405Gly) in NM_001060.6. No submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as uncertain significance. -
