Clinical History: A 45-year-old man of African ancestry with sickle cell disease presents with a delayed hemolytic transfusion reaction. Antibody screen reveals anti-Fy3. RBC phenotype is Fy(a–b–).  Question: What does the presence of anti-Fy3 suggest about this patient’s genotype? (M1.3)

A patient with chronic granulomatous disease presents with acanthocytosis and weak Kell antigen expression. Which genetic defect explains this? (M1.5)

A neonate’s red cells show Le(a−b−) phenotype. At 6 months, the phenotype shifts to Le(a+b−). What explains this transition? (M2.1) 

A patient’s RBCs type Lu(a–b–). Adsorption/elution shows trace Lub expression. No anti-Lu3 is produced. (M2.2)

Clinical History: A 38-year-old male with chronic granulomatous disease presents with mild hemolytic anemia and acanthocytosis. Antibody screen reveals anti-Kx and anti-Km. Kell antigen expression is weak. Question: What is the most likely genetic basis for this phenotype? (M1.5)

A Kell antibody reacts poorly in LISS but strongly in PEG-enhanced IAT. What does this suggest? (M1.2)

A patient with recessive Lu(a–b–) develops anti-Lu3.What units should be issued? (M1.5)

____________ removes redundant feature maps (channels) in convolutional neural networks (CNNs) that contribute minimally to the model’s performance.

When a machine learning models make predictions, it is referred to as:

The easiest way to understand any problem with your application is to attach a __________.
