A case of prenatal diagnosis of 16q24.3 microdeletion KBG syndrome and review of the literature

Abstract

Abstract Here we report a case of a 16q24.3 microdeletion KBG syndrome (KBGS) in a fetus. The absence of a well‐defined phenotype poses a challenge for genetic diagnosis. This report demonstrated that the high‐risk chromosome 21 trisomy could be the first manifestation of KBGS, as observed in this case.
