Note new association between missense variants located in a specific region of KMT2D spanning exons 38 and 39 and affecting highly conserved residues cause a novel multiple malformations syndrome distinct from Kabuki syndrome, through a dominant negative mechanism.
- >10 unrelated families with choanal atresia, athelia or hypoplastic nipples, branchial sinus abnormalities, neck pits, lacrimal duct anomalies, hearing loss, external ear malformations, and thyroid abnormalities. None of the individuals had intellectual disability.
