FOXN1 and coronary aneurysm: In summary, we sequenced the whole exomes of patients with KD and identified five candidate genes (FCRLA, PTGER4, IL17F, CARD11, and SIGLEC10) that may influence KD susceptibility, and another five candidate genes (FGFR4, IL31RA, FNDC1, MMP8, and FOXN1) with potential influence on the development of coronary aneurysms in KD.
