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]

Collection Method: clinical testing

The c.190A>G (p.T64A) alteration is located in exon 3 (coding exon 2) of the PEAR1 gene. This alteration results from a A to G substitution at nucleotide position 190, causing the threonine (T) at amino acid position 64 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
