Disease: Von-willebrand Disorder (2N)

Patient: 32 yo, male

Variant: VWF NM_000552.5 c:2527C>T, p.(Arg760Cys), exon 17, noted to be dominant effect

Note: Proband also has an Arg91Gln mutation in exon 20 of VWF too.

Phenotypes: Mild bleeding history, epistaxis, bleeding gums, bleeding after tooth extraction. 11 years old had severe hemorrhage following tonsillectomy. Previous diagnosis of hemophilia A.

Family: father has history of epistaxis but never eamined prior to study. Father has the Arg760Cys mutation at heterozygous level. Mother is asymptomatic and classified as hemophilia A carrier following hemophilia A diagnosis in son. Mother also has the Arg91Gln mutation in exon 20 at heterozygous level.

Molecular Phenotypes: mild decrease in plasma FVIII and VWF levels, normal platelet VWF content, decreased FVIII binding capacity of VWF. Causes retention of pro-VWF(suggest defects in the maturation process of VWF). Abnormal VWF and platelet GPIb interaction(documented by impaired or absent RIPA and decreased VWF:RCo).

Disease for patient 1: Von Willebrand Disease Type1, transmitter VWD-type 3

Disease for patient 2: Von Willebrand Disease Type 3

Patient1: 90 YO female (Afro-Caribbean)

Patient2: 40 YO female (Afro-Caribbean)

Notes multiple variants in the VWF gene but have focused on variants in the D4 domain. However cannot discount the impact of some other variants.

Variant 1: VWF NM_000552.5: c.6647del p.(Cys2216Phefs*9), results in VWF protein missing D4 domain and C-terminal end of molecule

Phenotype patient 1: Reduced VWF levels in VWF:Ag, VWF:ristocetin cofactor, FVIII:C, FVIII(VWF:FVIIIB). Bleeding score 0, required Helixate treatment before and after receiving surgery.

Variant 2: VWF NM_000552.5: c.6432dup p.(Pro2145Thrfs*5)

Three sequence variations in family study showed other variants highlighted p.(Cys1149Arg) and p.(Pro2145Thrfs*5) are not on the same allele.

Does have other variants in VWF but they are stated by authors to not be detrimental. p.(Val510=) is noted to be potentially deleterious.

Phenotype patient 2: severely reduced VWF levels, absence of multimers, bleeding score 32, epistaxis, bruising, oral cavity bleeding, prolonged bleeding from minor wounds, menorrhagia, hemarthrosis, ankle arthropathy.

Suggests premature termination codons in these variants may lead to NMD but that this mechanism was found to be PTC position-dependent. Degradation was not 100% and need to perform cellular experiments.

To examine the small mutations in the coding region of the OTC gene, all 10 exons and their flanking intron regions were amplified using PCR, and the nucleotide sequences of the amplified products were determined. To determine the intron 5 sequence of case 2, PCR was performed using primers OTCex5F and OTCint5R, and primers OTCint5F and OTCex6R (Table 1, Fig. 3). The amplified products were subcloned into the pT7 vector and the inserted DNA was sequenced using an automated DNA sequencer. Allopurinol test

Case Previous Testing: Total RNA was isolated from peripheral blood lymphocytes or lymphoblastoid cell lines and from frozen liver biopsy as described in Chomczynski and Sacchi (1987). For each patient two cDNA syntheses were performed: 10mg of total RNA with 800-1000 ng of oligo dT or 500ng of specific primer NR, mapping in the 3’UTR of OTC cDNA Identification of genetic lesions by amplification of the OTC mRNA, expressed in the liver tissue and intestine, from a non-specific tissue like PBL or lymphoblastoid cell lines. Some mutations, particularly those affecting splicing sites, may have a different expression in liver and PBL . In females, including manifesting carriers, this method allows the identification of deletions and gene rearrangements with certainty, but mutations, decreasing mRNA stability, are unlikely to be detected because the normal allele will constitute the majority of the RNA available for RT-PCR and will be preferentially amplified.

Supplemental Data: Case report section Notes: Hepatomegaly. This mutation, previously reported (Reish et al., 1993), has been correlated with a lethal disease form in a male patient, therefore the mild phenotype in our patient could be explained by a not completely unfavorable X-lyonization

Supplemental Data: Case report section Notes: Patient had a pregnancy 2 years prior and lost the baby. In this case report, She was a 14weeks pregnant(2nd pregnancy) 24yo . She died during this of severe hyperammonemia 5 days after being administered amino acids through parenteral nutrition. She developed signs of encephalopathy stage 4 with maximal dilated unresponsive pupils, brisk oculocephalic reflex, and severe hyperventilation, requiring mechanical ventilation. MRI revealed revealed diffuse cortical edema with loss of white to gray matter distinction. Increased excretion of Gly, Gln, Ser, Thr, and Lys was found in her urine.

In F patients, the deletions determined by the SALSA multiplex ligation probe amplification (MLPA) KIT P079 OTC (MRC-Holland, Amsterdam, the Netherlands) and the Affymetrix Human SNP 6.0 array (Santa Clara, CA). Sequence spanning 38,211,736 – 38,300,703 bp region on chromosome X (GRCh37) and including OTC was scanned for motifs CCTCCCT, CCTCCTT, CCTCCCTT, CCCCACCCC, CCNCCNTNNCCNC, GGNGGNAGGG and their complements known as being associated with recombination hotspots. Repeats capable of non-B DNA structure formation implicated in double strand breaks (DSBs) were sought by complexity analysis . X-inactivation ratio determined by analysis of methylation status of the human androgen-receptor locus (HUMARA)

Supplemental Data: Table 1&2, the minimum plasma ammonia, orotic acid and Gln+Glu concentrations depends on certain age range: Plasma ammonia: neonates <90μmol/l, other <60μmol/l. Urinary orotic acid: 0–1year <6.6mmol/mol creatinine, 1 – 10 years <3.5 mmol/mol creatinine, over 10 years <2.4 mmol/mol creatinine. Serum glutamate + glutamine: 0 – 1 month 200–1200μmol/l, 1 month–1year 200–1100μmol/l, 1year–18years 200–900μmol/l, over 18years 200–800μmol/l.
