Moreover, two protein-truncating PTPRJ alleles (p.T38Pfs9* and p.S626Afs7*) have recently been discovered in a study towards genes underlying inherited thrombocytopenia and, importantly, functional studies in zebrafish and mouse models underscored the important role for PTPRJ in platelet biogenesis (Senis et al., 2009; Marconi et al., 2019; Nagy et al., 2020). The gene discussed is PTPRJ; the disease is Thrombocytopenia.
