What gene causes prader willi syndrome? Prader-Willi syndrome is caused by a genetic problem on chromosome number 15. Genes contain the instructions for making a human being. They’re made up of DNA and packaged into strands called chromosomes. A person has 2 copies of all their genes, which means chromosomes come in pairs.
Is Prader-Willi syndrome recessive or dominant? Prader–Willi syndrome has autosomal dominant inheritance, (is inherited from one affected parent) and affects both sexes and all races. However, most cases are sporadic.
What is the genotype of Prader-Willi syndrome? Prader-Willi syndrome is due to absence of paternally expressed imprinted genes at 15q11. 2-q13 through paternal deletion of this region (65–75% of individuals), maternal uniparental disomy 15 (20–30%), or an imprinting defect (1–3%). Parent-specific DNA methylation analysis will detect >99% of individuals.
