Capillary malformation-arteriovenous malformation 2(CMAVM2)

MedGen UID:
1648502

C4748670
Disease or Syndrome
Synonym: CMAVM2
 
Gene (location): EPHB4 (7q22.1)

OMIM®: 618196

Disease characteristics

Capillary malformation-arteriovenous malformation (CM-AVM) syndrome is characterized by the presence of multiple small (1-2 cm in diameter) capillary malformations mostly localized on the face and limbs. Some affected individuals also have associated arteriovenous malformations (AVMs) and/or arteriovenous fistulas (AFVs), fast-flow vascular anomalies that typically arise in the skin, muscle, bone, spine, and brain; life-threatening complications of these lesions can include bleeding, congestive heart failure, and/or neurologic consequences. Symptoms from intracranial AVMs/AVFs appear to occur early in life. Several individuals have Parkes Weber syndrome (multiple micro-AVFs associated with a cutaneous capillary stain and excessive soft-tissue and skeletal growth of an affected limb). [from GeneReviews]

Additional description

From OMIM
Capillary malformation-arteriovenous malformation-2 (CMAVM2) is an autosomal dominant disorder with variable expressivity. Patients have small multifocal cutaneous capillary malformations (CMs) on the head, neck, trunk, and/or extremities, sometimes in association with arteriovenous malformations (AVMs), which are typically located in the brain, face, or extremities. Some affected individuals also exhibit Parkes Weber lesions of the extremities, and vein of Galen aneurysmal malformations (VGAMs) are present in some patients (Amyere et al., 2017). For a discussion of genetic heterogeneity of CMAVM, see 608354.  http://www.omim.org/entry/618196

Clinical features

From HPO
Vein of Galen aneurysmal malformation
MedGen UID:
140912
Concept ID:
C0431420
Disease or Syndrome
Vein of Galen aneurysmal malformation is a choroidal type of arteriovenous malformation that develops between 6 and 11 weeks of gestation. It results from 1 or more arteriovenous fistulas shunting blood toward the prosencephalic vein of Markowski, the embryonic precursor of the vein of Galen. This abnormal shunt leads to progressive dilation of the vein and prevents its involution and subsequent development into the vein of Galen.
Telangiectasia
MedGen UID:
21088
Concept ID:
C0039446
Finding
Telangiectasias refer to small dilated blood vessels located near the surface of the skin or mucous membranes, measuring between 0.5 and 1 millimeter in diameter. Telangiectasia are located especially on the tongue, lips, palate, fingers, face, conjunctiva, trunk, nail beds, and fingertips.
Capillary malformation
MedGen UID:
90955
Concept ID:
C0340803
Congenital Abnormality
A capillary malformation is a flat, sharply defined vascular stain of the skin. It may cover a large surface area or it may be scattered and appear as little islands of color. In a capillary maformation, the predominant vessels are small, slow-flow vessels (i.e., arterioles and postcapillary venules).
