Analytical Validity: Help
Loeys-Dietz syndrome (LDS) is primarily characterized by vascular findings (cerebral, thoracic, and abdominal arterial aneurysms and/or dissections) and skeletal manifestations (pectus excavatum or pectus carinatum, scoliosis, joint laxity, arachnodactyly, talipes equinovarus). DNA results are based on the analysis for the specific variant in the family using either Sanger sequencing or … View more
