Summary Summary


Listen
The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.
orphanet

Orpha Number: 90349

Definition
A generalized connective tissue disorder characterized by the association of wrinkled, redundant and sagging inelastic skin with severe systemic manifestations (lung atelectesias and emphysema, vascular anomalies, and gastrointestinal and genitourinary tract diverticuli).

Epidemiology
The prevalence of ARCL1 is unknown but around 60 cases have been reported in the literature so far.

Clinical description
The skin manifestations affect the whole body and are usually recognizable from birth. The excessive lax skin is particularly prominent around the axillae, groins and neck and on the face (giving patients an aged appearance with eyelid ptosis and drooping cheeks). Pulmonary emphysema develops early in life (during the neonatal period or by early childhood), often leading to respiratory failure. Common vascular anomalies include arterial aneurysms, fibromuscular artery dysplasia and stenosis leading to progressive heart failure. Genitourinary tract diverticuli lead to vesicoureteral reflux and recurrent infections. Less frequent findings include late closure of the fontanel, joint laxity, hip dislocation, inguinal hernia, arachnodactyly, bone fragility, vascular tortuosity and aortic aneurysm. Intelligence is normal.

Etiology
ARCL1 is genetically heterogeneous and, although the etiology remains unknown in the majority of cases, mutations have been identified in some patients in the FBLN5 (14q31) and EFEMP2 (11q13) genes, encoding the extracellular matrix proteins fibulin-5 and EGF-containing fibulin-like extracellular matrix protein 2 (Fibulin-4), respectively. Arachnodactyly, bone fragility, vascular tortuosity and aortic aneurysms are common findings in patients carrying EFEMP2 mutations.

Diagnostic methods
Detailed clinical evaluation and histological studies of skin biopsies (revealing a moth-eaten appearance, abnormal elastin fiber branching and lose microfibrils associated with reduced elastin synthesis) are usually diagnostic in ARCL1. Molecular testing, available on a research basis only, may confirm the diagnosis in carriers of FBLN5 and EFEMP2 mutations.

Differential diagnosis
The differential diagnosis should include other forms of CL (autosomal recessive type 2, autosomal dominant and X-lined CL) and related syndromes (gerodermia osteodysplastica, Cantu syndrome, wrinkly skin syndrome and De Barsy syndrome), together with the Ehlers-Danlos syndromes and Costello syndrome (see these terms).

Genetic counseling
Genetic counseling should be provided to affected families and prenatal diagnosis through molecular testing is feasible for families in which the disease-causing mutation has been identified.

Management and treatment
There are no effective therapeutic strategies available for ARCL1. Care should be multidisciplinary with symptomatic treatment of pulmonary emphysema, prophylactic therapy for infections and hernia repair.

Prognosis
The disease course in ARCL1 is severe, with most patients dying in childhood from cardiac or respiratory failure.

Symptoms Symptoms

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.
