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]

The c.1421G>C (p.R474P) alteration is located in exon 12 (coding exon 11) of the PEAR1 gene. This alteration results from a G to C substitution at nucleotide position 1421, causing the arginine (R) at amino acid position 474 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
