Similar duplications have been reported in individuals with a range of phenotypes, typically involving developmental delay, growth retardation, and various dysmorphic features (Battaglia 2005, Goodman 1997, Traub 2021). There are no similar copy number gain of this region in the general populations of the Database of Genomic Variants.
