PTPRJ and Kawasaki disease: Given CD148’s involvement in vasculogenesis and being also expressed in hematopoietic cells, in hindsight it seems logical that in a micro-array genotyping study (involving 164,395 SNPs, 119 Polish patients and over 6K controls) the polymorphism rs151078858 in PTPRJ was among the five that were most statistically linked with Kawasaki disease (Buda et al., 2021).
