- Congenital Abnormality
Aortic valve disease-2 (AOVD2) is characterized by bicuspid aortic valve (BAV) and dilation of the ascending aorta. Calcification of the valve and the aorta has been observed, and some patients exhibit coarctation of the aorta (Tan et al., 2012; Luyckx et al., 2019; Park et al., 2019).

Ischemic stroke- MedGen UID:
- 215292
- •Concept ID:
- C0948008
- •
- Disease or Syndrome
A stroke is an acute neurologic event leading to death of neural tissue of the brain and resulting in loss of motor, sensory and/or cognitive function. It is said to be the third leading cause of death in the United States. Gunel and Lifton (1996) noted that about 20% of strokes are hemorrhagic, resulting in bleeding into the brain. Ischemic strokes, resulting from vascular occlusion, account for the majority of strokes.
Bersano et al. (2008) reviewed genetic polymorphisms that have been implicated in the development of stroke. Candidate genes include those involved in hemostasis (see, e.g., F5; 612309), the renin-angiotensin-aldosterone system (see, e.g., ACE; 106180), homocysteine (see, e.g., MTHFR; 607093), and lipoprotein metabolism (see, e.g., APOE; 107741).
See also hemorrhagic stroke, or intracerebral hemorrhage (ICH; 614519).
Impaired distal tactile sensation- MedGen UID:
- 867225
- •Concept ID:
- C4021583
- •
- Finding
A reduced sense of touch (tactile sensation) on the skin of the distal limbs. This is usually tested with a wisp of cotton or a fine camel's hair brush, by asking patients to say 'now' each time they feel the stimulus.
Facial palsy- MedGen UID:
- 87660
- •Concept ID:
- C0376175
- •
- Disease or Syndrome
Facial nerve palsy is a dysfunction of cranial nerve VII (the facial nerve) that results in inability to control facial muscles on the affected side with weakness of the muscles of facial expression and eye closure. This can either be present in unilateral or bilateral form.
Lymphopenia- MedGen UID:
- 7418
- •Concept ID:
- C0024312
- •
- Disease or Syndrome
A reduced number of lymphocytes in the blood.
Decreased circulating total IgM- MedGen UID:
- 116095
- •Concept ID:
- C0239989
- •
- Finding
An abnormally decreased level of immunoglobulin M (IgM) in blood.
Antiphospholipid antibody positivity- MedGen UID:
- 866404
- •Concept ID:
- C4019436
- •
- Finding
The presence of circulating autoantibodies to phospholipids.
Livedo reticularis- MedGen UID:
- 43223
- •Concept ID:
- C0085642
- •
- Disease or Syndrome
Livedo reticularis is characterized by the presence of a bluish purple, mottled or netlike pattern in unbroken circles on the skin. Exposure to cold environments usually intensifies the vascular pattern. Presumably, the condition results from slow or stagnant blood flow, vessel-wall pathology, and decreased oxygen tension.
Atrophic scars- MedGen UID:
- 57875
- •Concept ID:
- C0162154
- •
- Pathologic Function
Scars that form a depression compared to the level of the surrounding skin because of damage to the collagen, fat or other tissues below the skin.
Cutis marmorata- MedGen UID:
- 78093
- •Concept ID:
- C0263401
- •
- Disease or Syndrome
A reticular discoloration of the skin with cyanotic (reddish-blue appearing) areas surrounding pale central areas due to dilation of capillary blood vessels and stagnation of blood within the vessels. Cutis marmorata generally occurs on the legs, arms and trunk and is often more severe in cold weather.
Livedo- MedGen UID:
- 568434
- •Concept ID:
- C0332579
- •
- Finding
A reddish-blue mottled condition of skin caused by inflammation of the cutaneous blood vessels.
Livedo racemosa- MedGen UID:
- 1778101
- •Concept ID:
- C5441660
- •
- Sign or Symptom
Livedo racemosa describes a reddish-blue mottling of the skin in an irregular, reticular pattern. It differs from the more common livedo reticularis by its shape. Livedo racemosa consists of broken circular segments resulting in a seemingly larger pattern, as opposed to the fine, regular, complete network of livedo reticularis. Livedo racemosa results from permanent impairment of peripheral blood flow and, unlike livedo reticularis, it persists on warming.
