The eQTL data that we present from control lung tissue shows that the minor allele A of rs62025270, associated with susceptibility to IPF, is also associated with increased expression of AKAP13 in three independent studies.53, 54, 55 The immunohistochemistry results provide evidence that the predominant cell types expressing AKAP13, in both normal and fibrotic lung, are epithelial cells and resident immune cells, whereas the dense fibrotic regions of lung with an expanded population of myofibroblasts (figure 5C–F) do not express AKAP13. Here, AKAP13 is linked to idiopathic pulmonary fibrosis.
