37978175 and 30578106: 5/114 probands with VOGM with EPHB4 variants. All variants transmitted, phenotype absent or milder in the parent carriers, suggests incomplete penetrance and variable expressivity. In vitro modelling of R838W, K650N and F867L in COS-7 (PMID 37978175) and HEK (PMID 30578106) cells showed reduced or absent protein tyrosine kinase activity of EPHB4.
29444212: Vein of Galen aneurysmal malformation, 5/51 patients with EPHB4 variant (only 2 had cutaneous CMs as an associated phenotype); 4 transmitted, suggests wide clinical spectrum. In vivo zebrafish ephb4a morphants show vascular abnormalities, rescuable by WT EPHB4 mRNA but not with an EPHB4 frameshift mimic mRNA.
39367533: 59 participants with CV-AVM, 1 patient with a brain AVM had an EPHB4 and an ACVRL1 variant.

New gene rated Amber - deemed relevant to the GMS panel R336 Cerebral vascular malformationsCreated: 29 Nov 2019, 3:43 p.m. | Last Modified: 29 Nov 2019, 3:43 p.m.
Panel Version: 1.59
Review from clinical expert (Vijeya Ganesan: GOSH / ICH): consider for this panel. GEL clinical team (Helen Brittain) Review of PMID 28687708 suggests that 3/110 patients had CNS lesions - therefore rated as amber pending further evidence
