Supravalvular aortic stenosis associated with a deletion disrupting the elastin gene.
DNA sequence analysis and pulsed-field, PCR, and Southern analyses indicate that mutations in the elastin gene cause SVAS and suggest thatElastin exons 28-36 may encode critical domains for vascular development.

Supravalvular aortic stenosis cosegregates with a familial 6; 7 translocation which disrupts the elastin gene.
This work reports on a family in which SVAS is cosegregating with a balanced reciprocal translocation, t(6:7) (p21.1;q11.23), providing further evidence that SVas is the result of a mutation of elastin at 7q 11.23 region.
Elastin: mutational spectrum in supravalvular aortic stenosis
The spectrum of mutations occurring in familial and sporadic SVAS is described and the mutational mechanisms involved in SVAS are attempted to define, to identify the four missense mutations identified.
Elastin point mutations cause an obstructive vascular disease, supravalvular aortic stenosis.
The data demonstrate that point mutations of ELN cause autosomal dominant SVAS, and ELN point mutations co-segregate with the disease in four familial cases and are associated with SVAS in three sporadic cases.
Novel mutations in the human elastin gene (ELN) causing isolated supravalvular aortic stenosis.
It is confirmed that functional haploinsufficiency of elastin is responsible for the pathogenesis associated with isolated SVAS across different ethnic backgrounds.
Supravalvular aortic stenosis: genetic and molecular dissection of a complex mutation in the elastin gene
Despite considerable variability in the molecular nature of mutations responsible for SVAS, the unifying mechanism appears to be the generation of null alleles by NMD leading to elastin haploinsufficiency.
A new mutation in the elastin gene causing supravalvular aortic stenosis.
Supravalvular aortic stenosis: a splice site mutation within the elastin gene results in reduced expression of two aberrantly spliced transcripts
This study demonstrates the expression of mutant alleles of the elastin gene in patients with isolated SVAS, and indicates that the mutations found in the two apparently non-overlapping kindreds are identical by descent.
Elastin Mutation and Cardiac Disease
This review considers the evidence relating Elastin mutations to SVAS and WS and outlines the possible mechanisms by which these mutations give rise to cardiac disease.

Findings indicate that a gene for supravalvular aortic stenosis is located in the same chromosomal subunit as elastin, which becomes a candidate for the disease gene.
Marfan syndrome caused by a recurrent de novo missense mutation in the fibrillin gene
Fibrillin is implicate as the protein defective in patients with the Marfan syndrome and a de novo missense mutation in the fibrillin gene is described in two patients with sporadic disease.

The following case is of interest in that Marfan's syndrome was accompanied by aortic stenosis of a type apparently not previously reported.
Supravalvular aortic stenosis. Clinical and pathologic observations in six patients.
Although hemodynamics during intrauterine development may predispose to localization of the stenosis to the supra-aortic valvar region, the cause for the mural dysplasia remains uncertain.

Genomic clones encompassing the entire human elastin gene, including 11 kilobases flanking the ATG translation initiation codon, have been obtained and characterized by restriction enzyme analysis
The material and discussion presented below is limited to the true stenosis, or coarctation, of the supravalvular aorta under this classification, and is concerned with the familial incidence of this malformation.
Human elastin gene: new evidence for localization to the long arm of chromosome 7.
The results indicate that the human elastin gene is located in the proximal region of the long arm of chromosome 7, which is useful in establishing genetic linkage between inheritance of an allele with a mutated elastIn gene and a heritable disorder.
Marfan syndrome: defective synthesis, secretion, and extracellular matrix formation of fibrillin by cultured dermal fibroblasts.
It is indicated that mutations in the gene that encodes fibrillin are responsible for the Marfan syndrome in the majority of individuals and that a variety of mutations can produce the phenotype associated with the syndrome.
