KMT2C and primary failure of tooth eruption: Variant (c.1013-2 A > G) in KMT2C was considered as a potentially pathogenic variant based on its segregation with the PFE phenotype in the family, absence of KMT2C variant in genetic variation databases, known association of KMT2C family members with the tooth development and morphogenesis and presence of the gene in the IBD region on chromosome 7.
