Genes affected

PROCR (HGNC:9452): (protein C receptor) The protein encoded by this gene is a receptor for activated protein C, a serine protease activated by and involved in the blood coagulation pathway. The encoded protein is an N-glycosylated type I membrane protein that enhances the activation of protein C. Mutations in this gene have been associated with venous thromboembolism and myocardial infarction, as well as with late fetal loss during pregnancy. The encoded protein may also play a role in malarial infection and has been associated with cancer. [provided by RefSeq, Jul 2013]

Apr 05, 2023

The c.554C>A (p.T185N) alteration is located in exon 3 (coding exon 3) of the PROCR gene. This alteration results from a C to A substitution at nucleotide position 554, causing the threonine (T) at amino acid position 185 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
