Case1: A 44-year old male of European (non-Finnish) ancestry.

DiseaseAssertion: Disease, with the MYL2 p.Ala13Thr variant.

FamilyInfo: Mother, father, and sister was diagnosed at different ages; they all had it.

ParentalTesting: Yes with screening by ECG and Echocardiography; underwent 12-lead electrocardiography (ECG), echocardiography (M-mode, 2D, and Doppler), and cardiac magnetic resonance imaging (CMR).

CaseHPOFreeText: Presented 3 years ago with persistent but mild chest pain and dyspnea. presence of II/VI mid-systolic murmur that increased with the Valsalva maneuver. Cardiac enzymes were negative for acute coronary syndromes. A 12-lead ECG was notable for sinus tachycardia at the rate of 104 bpm and evidence of left ventricular hypertrophy (LVH) with repolarization abnormalities. Myocardial stress perfusion tomography showed homogeneous distribution of the radiotracer in the myocardium. An echocardiogram showed a hyperdynamic left ventricle with moderate asymmetric septal hypertrophy, a maximum wall thickness of 1.8 cm. There was a resting left ventricular outflow tract (LVOT) gradient of 20 mmHg that increased to 40 mmHg upon Valsalva maneuver. CMR findings were notable for septal hypertrophy and diffuse patchy hyperenhancement, involving multiple myocardial walls. increasing dyspnea with a mild level of physical activity and chest pain. Evidence of LVH with repolarization abnormalities on a 12-lead ECG and a hyperdynamic left ventricle with a septal thickness of 2 cm, systolic anterior motion of mitral leaflets, mild to moderate mitral regurgitation, and an LVOT gradient of 100 mmHg on echocardiography (Figure 3A). Underwent surgical myectomy, which led to resolution of LVOT gradient and symptoms.

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)
