HUSP Clinical Genetics Laboratory, Hospital Universitario San Pedro De Logroño (HUSP) RCV004557271 SCV005046451 likely pathogenic Capillary malformation-arteriovenous malformation 2 criteria provided, single submitter clinical testing The variant was detected in a 64-years old woman with Rendu Osler suspicion. He presented the variant c.525C>G in exon 4 of EPHB4 in heterozygosity (NM_004444.5). It results in a premature termination codon, modifying the predicted protein (p.Tyr175Ter). This variant is not detected in general population and has not been reported in pathogenic data bases. Pathogenic variants in EPHB4 have been associated with Capillary malformation-arteriovenous malformation 2 (OMIM: 618196) and Lymphatic malformation 7 (OMIM: 617300) both with autosomal dominant inheritance. Capillary malformation-arteriovenous malformation 2 is characterized by arteriovenous malformations (cutaneous, subcutaneous, muscular and bone), Parkes Weber lesions of the extremities, multifocal cutaneous capillary malformations, Bier spots and telangiectasias. Capillary malformation-arteriovenous malformation 2 presents incomplete penetrance.
