Is chromosome 3p duplication inherited?

Chromosome 3p duplication can be de novo or inherited from a parent with a balanced translocation.[1][2]

"De novo" duplications occur sporadically as a random event during the formation of the egg or sperm. In these cases, a person would have no family history of the condition but could pass the duplication on to children.

Other cases of chromosome 3p duplication are the result of a balanced translocation in one of the parents. Carriers of a balanced translocation generally do not have any unusual symptoms or health problems; however, they have an increased risk of having children with a chromosome abnormality.
