Molecular analysis based on 15 short tandem repeats confirmed the size of the duplications and indicated that at least 1 of 15 loci has three alleles present. [ncbi.nlm.nih.gov]

These individuals present with nearly the same spectrum of findings as those individuals with the standard deletion. Chromosomes, which are present in the nucleus of human cells, carry the genetic information for each individual. [rarediseases.org]

Regardless if the deletion or duplication is present, no two affected people are ever exactly alike, and not every person with the deletion or duplication is affected in the same way. [perrysburghearingcenter.com]
