Patau syndrome, also known as trisomy 13, occurs when a person has an extra copy of chromosome 13. This typically arises from a random error during cell division in the formation of eggs or sperm, leading to a fertilized egg with three copies of chromosome 13 instead of the usual two. The risk of having a child with Patau syndrome increases with maternal age. It is not inherited in a typical Mendelian fashion, meaning it usually occurs sporadically rather than being passed down through families.
