Genes affected
EPHB4 (HGNC:3395): (EPH receptor B4) Ephrin receptors and their ligands, the ephrins, mediate numerous developmental processes, particularly in the nervous system. Based on their structures and sequence relationships, ephrins are divided into the ephrin-A (EFNA) class, which are anchored to the membrane by a glycosylphosphatidylinositol linkage, and the ephrin-B (EFNB) class, which are transmembrane proteins. The Eph family of receptors are divided into 2 groups based on the similarity of their extracellular domain sequences and their affinities for binding ephrin-A and ephrin-B ligands. Ephrin receptors make up the largest subgroup of the receptor tyrosine kinase (RTK) family. The protein encoded by this gene binds to ephrin-B2 and plays an essential role in vascular development.

Mar 29, 2019
SIB Swiss Institute of Bioinformatics
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:curation

This variant is interpreted as Uncertain significance for Capillary malformation-arteriovenous malformation 2. The following ACMG Tag(s) were applied: PM2: Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium. PP3: Multiple lines of computational evidence support a deleterious effect on the gene or gene product. PP1: Cosegregation with disease in multiple affected family members in a gene definitively known to cause the disease. -
