Piriformis Syndrome. Piriformis syndrome causes pain in the buttock which may radiate down the leg. It is due to the sciatic nerve being impinged by a tight piriformis muscle deep in the buttocks.he piriformis muscle is one of the small muscles deep in the buttocks that rotates the leg outwards. It runs from the sacrum bone at the bottom of the spine and attaches to the thigh bone or femur roughly near the outside crease of the buttocks.
Like Patau syndrome, Down syndrome is caused by having an extra copy of a certain chromosome. Individuals with Down syndrome usually have an extra copy of chromosome 21. Thus, Down syndrome is commonly called trisomy 21. Perhaps not surprisingly, the cause of the trisomy in both Patau and Down syndromes is similar. A phenomenon called nondisjunction is responsible for most cases of trisomy 13 and 21.
