The classical phenotype consists of characteristic facial features, supravalvular aortic stenosis, intellectual disability, overfriendliness, and visuospatial impairment. So far, 26-28 genes have been shown to contribute to the multisystem phenotype associated with Williams-Beuren syndrome. Among them, haploinsufficiency of the<i> ELN</i> gene has been shown to cause the cardiovascular anomalies. Identification of patients with atypical deletions has provided valuable information for genotype-phenotype correlation, in which other genes such as <i>LIMK1,</i><i>CLIP2, GTF2IRD1</i>, or <i>GTF2I</i> have been correlated with specific cognitive profiles or craniofacial features. Here, we report the clinical and molecular characteristics of a patient with an atypical deletion that does not include the <i>GTF2I </i>gene and only partially includes the <i>GTF2IRD1</i> gene. 2013-02-28 00:00:00 Deletion 7q11.23 Genomic disorders GTF2I GTF2IRD1 Segmental duplications Williams-Beuren syndrome Williams syndrome
