CasePreviousTesting: The Thrombosis-Hemostasis gene panel test used whole exome sequencing and included 99 diagnostic-grade genes (table 1 in PMID:36696193)

GenotypingMethod: WES using the coagulation subpanel of the UZ Leuven Thrombosis-Haemostasis gene panel test. WES was performed on the sequencing platform NovaSeq 6000 (Illumina), and Alissa Interpret software v5.2-5.4 (Agilent) was used for variant interpretation. Assessment of copy number variation was validated within the bioinformatics pipeline. The American College of Medical Genetics and Genomics and the Association of Molecular Pathology guidelines were used to classify variants as pathogenic (P), likely pathogenic (LP), a variant of uncertain significance (VUS), or (likely) benign (LB, B) variants

Case#: 40 yo, Female, W. Turkey

DiseaseAssertion: Glanzmann Thrombasthenia

FamilyInfo: Consanguineous (cousins).

ParentalGenotype: Both carriers.

CasePresentingHPOs: (HP:0007420) Spontaneous hematomas, (HP:0001892) Abnormal bleeding, (HP:0100608) Metrorrhagia, (HP:0001935) Microcytic anemia, (HP:0034263) Abnormal vaginal bleeding, (HP:0004944) Cerebral aneurysm,

PlateletAggregation: Hypochromic anemia and a platelet count of 198 × 109/L (normal range 150–400 × 109/L). Platelet aggregometry showed no aggregation after stimulation with collagen (2 and 10 µg/mL), ADP (4 and 10 µmol/L), and epinephrine (8 µmol/L) (norm > 70%), and reduced (42%, Norm > 70%) agglutination after stimulation with ristocetin (1.2 mg/mL).

CaseHPOFreeText: Received platelet concentrates multiple times as a young adult before dental surgery. Pregnancy, alloantibodies to glycoprotein αIIbβ3 were detected in the patient’s blood. emergency caesarean section was performed in another hospital. Because the patient developed severe bleeding problems, she received two red cell units, two pooled platelet concentrates, tranexamic acid, and desmopressin intraoperatively. Two drainages were placed. Three platelet concentrates were transfused in the following days, resulting in a first-time transfusion reaction. Emergency cesarean- endometrial coagulation, operative hysteroscopy.

ProteinExpression: Flow cytometry showed the absence of expression of CD41 (integrin αIIbβ3) and severely impaired fibrinogen binding after ADP activation

CasePreviousTesting: molecular genetic analysis was performed using a custom gene panel for inherited platelet disorders (Nextera Rapid Custom Enrichment, Illumina, San Diego, CA, USA) established in our department, followed by sequencing on a MiSeq (Illumina)

ProteinExpression: Flow cytrometric analysis revealed reduced levels of alphaIIbbeta3 on the surface of RM platelets (See Fig 1B)

PlateletAggregation: Ristocetin induced agglutination was normal; however, platelets failed to aggregate in response to all physiological agonists including ADP, collagen, epinephrine, thrombin, and arachidonic acid

CasePreviousTesting: Direct DNA sequence analysis of PCR amplified ITGA2B and ITGB3 genes from patient RM's genomic DNA was performed. All exons, including the immediate intron-exon junctions of ITGA2B and ITGB3 were amplified using the PCR primer pairs originating in the intron sequence flanking each exon. The resulting PCR fragments were purified and subjected to direct cycle sequencing
