We present a girl with full SMS phenotype. G-banding cytogenetic analysis showed normal 46,XX karyotype. Whole-genome array comparative genomic hybridization (CGH) was performed due to the severity of the phenotype and the unusual features present in the patient. An interstitial deletion in 17p11.2-p12, similar to 4.73 Mb in size was determined. Characteristic physical and behavioral phenotype strongly suggested SMS. This, to the best of our knowledge is the first patient with SMS reported in Turkey. We emphasize the need for whole genome analysis in multiple congenital abnormalities/mental retardation disorders with unusual and severe phenotypes.eninfo:eu-repo/semantics/closedAccessSmith-Magenis Syndrome17p11.2-p12 Interstitial DeletionArray Comparative Denomic HybridizationA Turkish patient with large 17p11.2 deletion presenting with Smith Magenis syndromeArticle2211119216149832-s2.0-79955698280N/AWOS:000289751600002Q4
