Genes affected

PEAR1 (HGNC:33631): (platelet endothelial aggregation receptor 1) PEAR1 is a platelet receptor that signals upon the formation of platelet-platelet contacts independent of platelet activation and secondary to platelet aggregation (Nanda et al., 2005 [PubMed 15851471]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.5).
• BP6: Variant 1-156908754-G-A is Benign according to our data. Variant chr1-156908754-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 2639470.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=3.39 with no splicing effect.
