We aimed to describe the clinical and genetic characteristics of 16 individuals with KBG syndrome (KBGS) from 13 Indian families. We retrospectively analyzed the clinical details of individuals with KBGS harboring a likely pathogenic/pathogenic variant in ANKRD11. We also analyzed their facial gestalt using Face2Gene and recorded the top three differential disorders suggested by the application. The most frequent clinical features observed in our cohort were as follows: learning and intellectual disability-14/15 (93%), skeletal abnormalities-14/15 (93%), postnatal short stature-13/15 (87%), brachydactyly-11/15 (73%), and characteristic facial appearance-13/15 (87%). We identified 12 single nucleotide variants (SNVs), including six recurrent and six novel variants, and a copy number variant in the 16q24.3 region encompassing ANKRD11 gene. The novel variants were as follows: p.(Gln1236Ter), p.(Asp884ThrfsTer93), p.(Arg1466GlyfsTer87), p.(Tyr2056Ter), p.(Leu955TrpfsTer22), and p.(Lys766ArgfsTer10). The identified SNVs in ANKRD11 clustered around exon 9. We observed a high concordance of Face2Gene in predicting KBGS.
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 .
