Interestingly, in the literature there are a series of microdeletions centromeric to KCNJ2/KCNJ16 that have been identified in individuals with congenital generalized hypertrichosis with or without gingival hyperplasia (microdeletion 17q24.2-q24.3 syndrome; MIM 135400; Figure S8). Here, KCNJ2 is linked to gingival disorder.
