Case: Female, Caucasian, 11 years at diagnosis

DiseaseAssertion: VWD1

FamilyInfo: Non-consanguineous family, parents carry no bleeding history but have risk factors (prolonged closure time and modestly decreased VWF:Ag level)

ParentalGenotype(s): Mother has c.7464C>T, Father carries no mutation.

CasePresentingHPOs: HP:0000421, HP:0000978, HP:0001934, HP:0030140, HP:0004846, HP:0006298

CaseHPOFreeText: Cumulative bleeding score of 17, Reduced VWF:Ag of 9IU/dL, VWF:GPIb of 6 I/dL, and factor VIII coagulant activity of 35 IU/dL, prolonged PFA closure time of >300 and reduced concentration of all multimers.

CaseNOTHPOs: None reported

CaseNOTHPOFreeText: Normal multimer size distribution (tested in Agarose gel)

CasePreviousTesting: NA

GenotypingMethod: Direct sequencing of genomic DNA exons 1 to 52, exon/intron boundaries, 5' and 3' UTR, promoter region, and whole intron 44 of VWF. RT-PCR followed by sequencing of cDNA to detect splicing defect due to c.7464C>T.
