Genes affected

PROZ (HGNC:9460): (protein Z, vitamin K dependent plasma glycoprotein) This gene encodes a liver vitamin K-dependent glycoprotein that is synthesized in the liver and secreted into the plasma. The encoded protein plays a role in regulating blood coagulation by complexing with protein Z-dependent protease inhibitor to directly inhibit activated factor X at the phospholipid surface. Deficiencies in this protein are associated with an increased risk of ischemic arterial diseases and fetal loss. Mutations in this gene are the cause of protein Z deficiency. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Jan 2012]

Ambry Genetics

Aug 13, 2021

The c.269C>G (p.P90R) alteration is located in exon 4 (coding exon 4) of the PROZ gene. This alteration results from a C to G substitution at nucleotide position 269, causing the proline (P) at amino acid position 90 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
