Disease characteristics

Excerpted from the GeneReview: FBLN5-Related Cutis Laxa
FBLN5-related cutis laxa is characterized by cutis laxa, early childhood-onset pulmonary emphysema, peripheral pulmonary artery stenosis, and other evidence of a generalized connective disorder such as inguinal hernias and hollow viscus diverticula (e.g., intestine, bladder). Occasionally, supravalvar aortic stenosis is observed. Intrafamilial variability in age of onset is observed. Cardiorespiratory failure from complications of pulmonary emphysema (respiratory or cardiac insufficiency) is the most common cause of death. [from GeneReviews]

MedGen UID:
2001
Concept ID:
C0003499
Disease or Syndrome
Supravalvular aortic stenosis (SVAS) is a heart defect that develops before birth. This defect is a narrowing (stenosis) of the large blood vessel that carries blood from the heart to the rest of the body (the aorta). The condition is described as supravalvular because the section of the aorta that is narrowed is located just above the valve that connects the aorta with the heart (the aortic valve). Some people with SVAS also have defects in other blood vessels, most commonly stenosis of the artery from the heart to the lungs (the pulmonary artery). An abnormal heart sound during a heartbeat (heart murmur) can often be heard during a chest exam. If SVAS is not treated, the aortic narrowing can lead to shortness of breath, chest pain, and ultimately heart failure.\n\nThe severity of SVAS varies considerably, even among family members. Some affected individuals die in infancy, while others never experience symptoms of the disorder.
Ascending tubular aorta aneurysm
MedGen UID:
163631
Concept ID:
C0856747
Anatomical Abnormality
An abnormal localized widening (dilatation) of the tubular part of the ascending aorta.
Vascular tortuosity
MedGen UID:
388724
Concept ID:
C2673776
Finding
Abnormal twisting of arteries or veins.
Overgrowth
MedGen UID:
376550
Concept ID:
C1849265
Finding
Excessive postnatal growth which may comprise increased weight, increased length, and/or increased head circumference.
Inguinal hernia
MedGen UID:
6817
Concept ID:
C0019294
Finding
Protrusion of the contents of the abdominal cavity through the inguinal canal.
Umbilical hernia
MedGen UID:
9232
Concept ID:
C0019322
Anatomical Abnormality
Protrusion of abdominal contents through a defect in the abdominal wall musculature around the umbilicus. Skin and subcutaneous tissue overlie the defect.
Congenital diaphragmatic hernia
MedGen UID:
68625
Concept ID:
C0235833
Congenital Abnormality
The presence of a hernia of the diaphragm present at birth.
Joint hypermobility
MedGen UID:
336793
Concept ID:
C1844820
Finding
The capability that a joint (or a group of joints) has to move, passively and/or actively, beyond normal limits along physiological axes.
Pectus excavatum
MedGen UID:
781174
Concept ID:
C2051831
Finding
A defect of the chest wall characterized by a depression of the sternum, giving the chest ("pectus") a caved-in ("excavatum") appearance.
Microcephaly
MedGen UID:
1644158
Concept ID:
C4551563
Finding
Head circumference below 2 standard deviations below the mean for age and gender.
Emphysema
MedGen UID:
18764
Concept ID:
C0034067
Disease or Syndrome
A subcategory of chronic obstructive pulmonary disease (COPD). It occurs in people who smoke and suffer from chronic bronchitis. It is characterized by inflation of the alveoli, alveolar wall damage, and reduction in the number of alveoli, resulting in difficulty breathing.
Recurrent respiratory infections
MedGen UID:
812812
Concept ID:
C3806482
Finding
An increased susceptibility to respiratory infections as manifested by a history of recurrent respiratory infections.
Abnormality of the face
MedGen UID:
871375
Concept ID:
C4025871
Anatomical Abnormality
An abnormality of the face.
Cutis laxa
MedGen UID:
8206
Concept ID:
C0010495
Disease or Syndrome
Wrinkled, redundant, inelastic and sagging skin.
Redundant skin
MedGen UID:
154379
Concept ID:
C0581342
Pathologic Function
Loose and sagging skin often associated with loss of skin elasticity.
Abnormal cutaneous elastic fiber morphology
MedGen UID:
1369253
Concept ID:
C4476582
Anatomical Abnormality
