Moreover, connections of COVID-19 to hematologic diseases have been found, especially to those causing anemia, thrombocytopenia and other blood cell anomalies, caused by mutations or deficiencies in genes WAS, FYB1, SRC, among others (Supplementary Material, Tables S2 and S3), causing diseases such as X-linked severe congenital neutropenia (ORPHA:86788, HP:0001875 and HP:0002718), Congenital autosomal recessive small-platelet thrombocytopenia (ORPHA:566192) or Hereditary thrombocytopenia with early-onset myelofibrosis (ORPHA:480851), respectively. Here, WAS is linked to myelofibrosis.
