NCIt definition : Human ELN wild-type allele is located in the vicinity of 7q11.23 and is approximately
42 kb in length. This allele, which encodes elastin protein, plays a role in the regulation
of the structure of the extracellular matrix. Mutations in the gene are associated
with autosomal dominant cutis laxa and supravalvular aortic stenosis. Haploinsufficiency
may be a factor in Williams-Beuren syndrome.;
