Third, slc34a2 encodes a phosphate carrier protein involved in cellular homeostasis of inorganic phosphate (Hilfiker et al. 1998; Werner et al. 2016) and was found in proximity to the peak on chromosome 10 and was reported to have higher expression in the head‐kidney of AGD susceptible fish (Robledo et al. 2020). Here, SLC34A2 is linked to argyrophilic grain disease.
