Key Points

This case aims to explore the complications arising from atypical presentations of von Willebrand disease (VWD) in a newborn.
Detailed clinical evaluation of the newborn's bleeding symptoms.
Comprehensive laboratory tests for factor VIII and VWD.
Genetic analysis to identify novel variants linked to VWD.
Detected low factor VIII activity in the newborn.
Characterized the disease as a combination of Type 2A and Type 2N VWD.
Highlighted the need for tailored diagnostic strategies in complex bleeding cases.
