Prominent and elongated coccyx, a new manifestation of KBG syndrome associated with novel mutation in ANKRD11

KBG syndrome is characterized by short stature, distinctive facial features, and developmental/cognitive delay and is caused by mutations in ANKRD11 , one of the ankyrin repeat‐containing cofactors. After the advent of whole exome sequencing, the number of clinical reports with KBG diagnosis has increased, leading to a revision of the phenotypic spectrum associated with this syndrome. Here, we report a female child showing clinical features of...
