Phosphorus, a mineral that is stored in bones, is responsible for maintaining cellular energy (the 'P' in ATP). Too much phosphorus, however, puts individuals with kidney disease at risk of cardiovascular events. On the flip side, low phosphorus is also in itself a disorder and has been shown to be caused by mutations along the mineral's metabolic pathways.
One paper has linked seven gene loci in multiple chromosomes to levels of phosphorus in the blood, three of which were located near known genes that code for proteins involved in metabolizing phosphorus. Read more here: http://www.ncbi.nlm.nih.gov/pubmed/20558539
