What does UPD mean?
- Uniparental disomy
- Uniparental disomy occurs when a person receives two copies of a chromosome, or of part of a chromosome, from one parent and no copies from the other parent. UPD can be the result of heterodisomy, in which a pair of non-identical chromosomes are inherited from one parent or isodisomy, in which a single chromosome from one parent is duplicated. Because it may lead to the duplication of lethal recessive genes, isodisomy is potentially dangerous, while heterodisomy is essentially benign.
