K abuki syndrome ( KS ) is a rare congenital anomaly syndrome characterized by a unique facial appearance, growth retardation, skeletal abnormalities, and intellectual disability. In 2010, MLL 2 was identified as a causative gene. On the basis of published reports, 55–80% of KS cases can be explained by MLL 2 abnormalities. Recently, de novo deletion of KDM 6 A has been reported in three KS patients, but point mutations of KDM 6 A have never been found. In this study, we investigated KDM 6 A in 32 KS patients without an MLL 2 mutation. We identified two nonsense mutations and one 3‐bp deletion of KDM 6 A in three KS cases. This is the first report of KDM 6 A point mutations associated with KS .
