      PMID: 33134807

      Gene: VWF

      HGNCID:12726

      Case: Female patient from the French Caribbean island of Martinique

      DiseaseAssertion: VWF Type 3

      FamilyInfo: The proband had a combination of two variants p.(Val510+) and p.(Pro21452145Thrfs*5) in a heterozygous state. Her biological profile indicated VWD3: VWF:Ag = 1 to 5%, VWF:RCo = 5%, FVIII:C = 2 to 3%, VWFpp = 6%, and a total absence of multimers assessed by electrophoresis. She was usually treated with plasma-derived VWF concentrates. Interestingly, the VWFpp level in this patient was higher than expected for typical VWD3. The sister who died from a nonhemorrhagic cause had the same clinical-biological profile.

      ParentalGenotype(s): The mother had a normal biological assessment and was asymptomatic without any bleeding. Sequencing of the mother's VWF gene revealed a single variant on exon 37: resulting in the nucleotide change c.6432dup / a.a. change p.(Pro2145THRfs*5) which results in a stop codon. This molecular abnormality favors VWD3, even though the mother is asymptomatic. The father experienced excessive bleeding only as a result of trauma or surgery. Sequencing of the father's VWF gene led to the identification of one potential causative variant: p.(Val510 = ), on exon 13 with a nucleotide change c.1530G>A. A second sister of the proband has a clinical and biological phenotype similar to that of her father.

      CasePresentingHPOs:HP:0012147, HP:0030132, HP:0030129

      CaseHPOFreeText: The proband presented with severe hemorrhagic manifestations.

      CaseSubsequentTesting:N/A

      GenotypingMethod:NGS

      PreviouslyPublished: No

      SupplementalData: The prediction softwares used (SpliceSiteFinder-like, MaxEntScan, GeneSplicer, NSPLICE, ESEFinder, RESCUE-ESE, and EX-SKIP) regarding c.1530G > A (p.(Val510 = )) interpreted the appearance of a donor site at 6 base pairs at the end of exon 13 which could potentially alter splicing. This synonymous mutation could therefore have an effect on VWF messenger ribonucleic acid processing, causing a shift in the reading frame and the appearance of a termination codon deletion of two codons. The ACMG predicted that this variant would probably be pathogenic.

      VariantEvidence: An additional 21 patients from Martinique were identified with the p.(Val510=) variant. Median age was 63 years (interquartile range [IQR], 45–77) and 65% were female. The striking feature in these patients was a significantly increased VWFpp/VWF:Ag ratio with a median of 5.62 (IQR, 4.36–6,14). This ratio could be calculated only for the 14 patients for whom the VWFpp level was measured. An increased VWFpp/VWF:Ag ratio (> 2.2) is indicative of an accelerated clearance of VWF. Addition testing in four patients involved DDAVP infusion compared to a patient with a VWD1 mutation that does not cause a clearance defect. The results showed accelerated VWF clearance compared to the control. The author propose to classify patient with the p.(Val510=) variant as Type 1C, a rare subtype that removes VWF more quickly than normal in the blood.

      Bioinformatic analyses of an SQL-based database containing 12272 variants that appear in 178 IRD genes in 5706 individuals of Ashkenazi Jewish origin based on the gnomAD database (version 2) and variants that were published in the scientific literature that was extracted from HGMD. Authors extracted information regarding IRD variants from various sources (including data of 5706 Ashkenazi Jewish (AJ) samples and a large cohort of Israeli patients with IRDs) to estimate carrier frequency of IRD mutations in different subpopulations in Israel. Two major databases aiming to estimate carrier frequency of IRD mutations in the Israeli population (Fig. 1): “gnomAD-AJ-IRD DB” containing data of 5706 AJ controls extracted from gnomAD and “HW-IRD DB” containing data extracted from our cohort of Israeli patients with IRDs.

      See Fig 2 for breakdown of variants analyzed.

      The final DB (IRDB) (Fig. 1 and Table S7) includes all 399 variants from “gnomAD-AJ-IRD DB” and “HW-IRD DB” that were considered here as pathogenic mutations in 111 known IRD genes.

      To establish the “HW-IRD DB” (Fig. 1), we collected data on Israeli IRD patients with a known cause of disease (a cohort of >2000 IRD families). The HW-IRD DB includes 289 pathogenic mutations (Fig. 1) that were identified in IRD patients who have biallelic variants.

      SupplementalData: S7, carrier frequency data for each mutation in all nine studied subpopulations. Carrier frequency was calculated as 2pq where p = 1 − q and q was calculated as the root square of the number of homozygous patients plus half the number of compound heterozygous patients divided by the population size
