ITGA2 and liver disorder: Most patients (≥ 83%) with pathognomonic LTA abnormalities from either BSS, suspected ITGA2/ITGB3‐RT or type 2B VWD, and the two patients with suspected MYH9RD (PLPRP: 45–59 × 109 platelets/L), had been evaluated with PLPRP containing ≤ 80 × 109 platelets/L, whereas most patients with some other disorders had been evaluated with PLPRP that had much higher platelet counts (e.g., those with: FPDMM, Quebec platelet disorder, TUBB1‐related thrombocytopenia, Jacobsen syndrome, thrombocytopenia from liver disease, or non‐diagnostic findings) (Tables 2, S2).
