A cross-sectional study in Australia found major risk factors for sarcopenia, such as low phosphate and serum albumin, in 39 dialysis patients with a median age of 69 years; patients with sarcopenia showed slightly greater calcium, PTH, and 25OH-D levels than the non-sarcopenic group, but the links between those measures and sarcopenia were not statistically significant [154]. The gene discussed is PTH; the disease is sarcopenia.
