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]

ACMG classification

Verdict is Benign. Variant got -21 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=1.3116118E-5).
• BP6: Variant 19-3595925-G-A is Benign according to our data. Variant chr19-3595925-G-A is described in ClinVar as [Benign]. Clinvar id is 263268.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=0.249 with no splicing effect.
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.589 is higher than 0.05.
