Test & specimen information
Uni-parental disomy
Overview
We all have 23 pairs of chromosomes with one chromosome of each pair coming from each parent. Uni-parental disomy (UPD) occurs when both copies of the one chromosome come from one parent. For most chromosomes this does not affect how we develop. But for a small group of chromosomes this can lead to imprinting disorders. UPD of chromosomes 6,7,11,14 and 15 are known to be associated with genetic conditions.
