Introduction to Uniparental Disomy of Chromosome 13
Introduction to Uniparental Disomy of Chromosome 13
The study reports a rare case of a homozygous variant in the LRBA gene with paternal origin. A case of maternal uniparental disomy of chromosome 13 is also described.
Definition of Uniparental Disomy
Uniparental disomy (UPD) is a genetic condition where an individual inherits two copies of a chromosome, or parts of a chromosome, from one parent instead of one copy from each parent. UPD can result from various mechanisms and may have implications for health and development. Understanding UPD is crucial in the context of genetic disorders and clinical diagnostics.
Overview of Chromosome 13 and its Role in Uniparental Disomy
Chromosome 13 is associated with unique characteristics in the context of uniparental disomy, highlighting the importance of understanding the genetic mechanisms involved.
