    Assay discrepancy in mild haemophilia A due to a factor VIII missense mutation (Asn694Ile) in a large Danish family
    1
    1. ClingenBaseline 24 Oct 2026
      Today, the Danish family consists of 275 known persons, all of whom are the offspring of six original proband siblings born in the middle of the nineteenth century ( Fig 1); at present, 28 living cases of mild haemophilia are known in the family. A cousin-to-cousin marriage of an affected male haemophiliac and an obligate carrier resulted in four sisters homozygous for the haemophilic mutation.

      Case#: 8, male

      DiseaseAssertion: Hemophilia A, mild

      FamilyInfo: Proband's mother and sister are confirmed carriers of hemophilia

      ParentalTesting: Mother was tested and found to be a carrier of hemophilia

      CasePresentingHPOs: HP:0003125

      CasePreviousTesting: For exons 1–13 and 15–26, PCR primers were designed for denaturing gradient gel electrophoresis (DGGE) and exon 14 was amplified in four overlapping fragments and subsequently sequenced. VWF:Ag was tested and found to be within normal ranges.

    Diagnostic importance of the two-stage factor VIII:C assay demonstrated by a case of mild haemophilia associated with His1954 → Leu substitution in the factor VIII A3 domain
    1
    1. ClingenBaseline 22 Oct 2026
      The patient was born in 1944; at the age of 7 he underwent a tonsillectomy, bled excessively and required a blood transfusion. He had dental extractions when he was 14 and bled for a week afterwards. At 25 he had a birthmark removed from his left shoulder and again bled excessively. At that time two-stage FVIII:C assays were performed and he was diagnosed as having mild haemophilia A with a FVIII:C level of 19%. 3 years later (in 1972) he presented with a large haematoma of the buttock after minor trauma and a two-stage assay reported a FVIII:C level of 11%. Interestingly, his APTT was always normal. In 1977 he had sebaceous cysts removed under the cover of FVIII concentrate. He received further concentrate in 1982 following an injury to his left thigh and 6 weeks later developed hepatitis (in retrospect hepatitis C). He has not had any further bleeding problems. At a recent routine visit his baseline FVIII:C level was checked with our (now routine) one-stage assay and found to be normal. Subsequently on three blood samples taken on different days we obtained the assay results shown in Table I. On the second of these samples the factor VIII antigen was measured by Immunozym ELISA (Techniclone, Dorking) and found to be 82 iu/dl.
