Pseudoxanthoma elasticum (PXE), also known as Grönblad–Strandberg syndrome, is a genetic disease that causes fragmentation and mineralization of elastic fibers in some tissues, typically affecting the skin first. Over 80% of the DNA variations leading to PXE are in the ABCC6 gene, and the disorder is typically inherited as an autosomal recessive condition. Wikipedia
