This incidence is comparable to published pediatric and mixed-age IT cohorts, where MYH9-RD ranges from 20 to 40% of inherited thrombocytopenia cases (23% in the Italian registry, 22–33% in East Asian pediatric cohorts, and ~30% in large multigene IT sequencing series) [3,7,8]. Here, MYH9 is linked to Thrombocytopenia.
