ABSTRACT
<p><b>OBJECTIVE</b>To perform genetic analysis for two patients with supravalvular aortic stenosis and unusual facial features.</p><p><b>METHODS</b>Cytogenetic and molecular genetic methods including chromosome karyotyping, multiplex ligation-dependent probe amplification (MLPA) and single nucleotide polymorphism array (SNP-array) were performed to detect potential mutation in the patients.</p><p><b>RESULTS</b>No abnormal karyotype was detected in either patient. Deletions in 7q11.23 region (1.36 Mb and 1.73 Mb, respectively) were discovered by SNP-array for the two patients. In both patients, de novo heterozygous deletion of ELN and LIMK1 genes was confirmed by MLPA analysis.</p><p><b>CONCLUSION</b>The genotypes of the two patients were identified by molecular genetic analysis, which has facilitated interpretation of the phenotypes of these patient. According to the deletion mutation, prenatal diagnosis for the family could be performed in the future.</p>
