Genes affected
ANXA5 (HGNC:543): (annexin A5) The Annexin 5 gene spans 29 kb containing 13 exons, and encodes a single transcript of approximately 1.6 kb and a protein product with a molecular weight of about 35 kDa.The protein encoded by this gene belongs to the annexin family of calcium-dependent phospholipid binding proteins some of which have been implicated in membrane-related events along exocytotic and endocytotic pathways. Annexin 5 is a phospholipase A2 and protein kinase C inhibitory protein with calcium channel activity and a potential role in cellular signal transduction, inflammation, growth and differentiation. Annexin 5 has also been described as placental anticoagulant protein I, vascular anticoagulant-alpha, endonexin II, lipocortin V, placental protein 4 and anchorin CII. Polymorphisms in this gene have been implicated in various obstetric complications. [provided by RefSeq, Dec 2019]

Uncertain significance, criteria provided, single submitter | clinical testing | Neuberg Centre For Genomic Medicine, NCGM | - | The missense c.652G>C p.Gly218Arg variant in ANXA5 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The p.Gly218Arg variant is reported with an allele frequency of 0.0004% in the gnomAD exomes database and is novel not in any individuals in 1000 Genomes database. This variant has not been reported to the ClinVar database. The amino acid change p.Gly218Arg in ANXA5 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The amino acid Gly at position 218 is changed to a Arg changing protein sequence and it might alter its composition and physico-chemical properties. For these reasons, this variant has been classified as a Variant of Uncertain Significance VUS. - |
