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 -10 ACMG points.

• BP6: Variant 19-3595078-TAA-T is Benign according to our data. Variant chr19-3595078-TAA-T is described in ClinVar as [Likely_benign]. Clinvar id is 1207313.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.0319 (10806/338606) while in subpopulation EAS AF= 0.0496 (957/19298). AF 95% confidence interval is 0.047. There are 0 homozygotes in gnomad4_exome. There are 5871 alleles in male gnomad4_exome subpopulation. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 12 AD gene.
