Phenotypic spectrum and tumor risk in Simpson-Golabi-Behmel syndrome: Case series and comprehensive literature review.
Simpson-Golabi-Behmel syndrome (SGBS) is a rare congenital overgrowth condition characterized by macrosomia, macroglossia, coarse facial features, and development delays. It is caused by pathogenic variants in the GPC3 gene on chromosome Xq26.2. Here, we performed a comprehensive literature review and phenotyping of known patients with molecularly confirmed SGBS and reviewed a novel cohort of 22 patients. Using these data, we characterized the tumor risk for Wilms tumor and hepatoblastoma to suggest appropriate screening for this patient population. In addition, we discuss the phenotypic overlap between SGBS and Beckwith-Wiedemann Spectrum.
期刊介绍：
The American Journal of Medical Genetics - Part A (AJMG) gives you continuous coverage of all biological and medical aspects of genetic disorders and birth defects, as well as in-depth documentation of phenotype analysis within the current context of genotype/phenotype correlations. In addition to Part A , AJMG also publishes two other parts:
Part B: Neuropsychiatric Genetics , covering experimental and clinical investigations of the genetic mechanisms underlying neurologic and psychiatric disorders.
Part C: Seminars in Medical Genetics , guest-edited collections of thematic reviews of topical interest to the readership of AJMG .
