Expected PCR product length without SINE 285 bp, with SINE ~506 bp. In this study, we report phenotypic and genotypic data from 1,410 independent HA families comprising about 82% of Italian HA patients. These data strengthen the relevance for a National Hemophilia Registry that is expected to considerably improve the medical care of HA families in Italy with respect to treatment and genetic counseling. Lozier J.N., Dutra A., Pak E., Zhou N., Zheng Z., Nichols T.C., Bellinger D.A., Read M., Morgan R.A. The Chapel Hill hemophilia A dog colony exhibits a factor VIII gene inversion.

  • A missense mutation was identified in 16%, 68%, and 81% of severe, moderate, or mild HA, respectively.
  • The disease is characterized by the lack or diminished activity of Factor VIII , caused by variants in the F8 gene and inherited as an X chromosomal trait.
  • Where n_e, n_s, and n_a are from the cryptographic context.
  • To provide a National database, 1,410 unrelated hemophilia A patients were investigated using screening methods denaturing high-performance liquid chromatography , conformational-sensitive gel electrophoresis ] and/or direct sequencing.
  • Both the altered splicing and the altered translation would lead to a protein with a mutated or missing light chain.

Hemophilia A is the most common coagulation factor disorder in humans and dogs. The disease is characterized by the lack or diminished activity of Factor VIII , caused by variants in the F8 gene and inherited as an X chromosomal trait. Two related male Rhodesian Ridgebacks were diagnosed with Hemophilia A due to reduced FVIII activity. The purpose of the study was to determine the genetic cause and give breeding advice for the remaining family members in order to eradicate the variant. By Sanger sequencing a short interspersed nuclear element insertion in exon 14 of the F8 gene was found. The identification of clinically unaffected female carriers allows subsequent exclusion of these animals from breeding, to avoid future production of clinically affected male offspring and more subclinical female carriers.

1. Clinical Presentation (Case Report)

We report herein the largest series of F8 analysis in HA patients issued in Italy. The vast majority of Italian families with HA, especially those with the severe cases, were included in this study, and it may be considered to be representative for the purpose of a population-based study of mutational heterogeneity. Actually, we were able to find 384 different mutations among 1,410 unrelated families.

In accordance with previous data, more than 25% of these unrelated families of our cohort presented a novel mutation (Ljung and Sjorin 1999; Habart et al. 2003; Oldenburg and Pavlova 2006). This reflects the high degree of heterogeneity of the F8-affecting mutations outside inversion of introns 22 and 1. Our study confirms the well-known correlation between the type of mutation and the severity of HA. The type of mutations found was in agreement with results reported in other settings (Oldenburg and Pavlova 2006; Fernández-López et al. 2005; Jayandharan et al. 2005; Deszo et al. 2006).

A total of 14 kb of the F8 gene, including the entire coding sequence, exon–intron junctions, and part of the 5′ and 3′ untranslated regions, were amplified by PCR. Most of the primers and amplification conditions have been previously reported; primer sequences, annealing temperatures, and the size of PCR fragments are available on request. A blood sample (5–10 mL) was collected in ethylenediaminetetraacetate or sodium citrate from each patient and stored at −20°C until sent to one of the nine laboratories that performed the genetic analysis. Isolation of DNA from leukocytes was carried out according to standard procedures (Miller et al. 1988). Jagannathan V., Drögemüller C., Leeb T., Dog Biomedical Variant Database Consortium A comprehensive biomedical variant catalogue based on whole genome sequences of 582 dogs and eight wolves. One male sibling had a history of acute onset coughing and severe dyspnea, without hyperthermia, at 8 weeks of age.

In Rhodesian Ridgebacks, hemophilia B resulting from a genetic variant in F9 gene is well known and genetic screening of breeding animals is common . However, in the winter of 2019, an 8-week-old male Rhodesian Ridgeback was presented with hemophilia A at the University Animal Hospital at the Norwegian University of Life Sciences. A retrospective investigation into the clinical history of male siblings, followed by clinicopathological testing where possible, confirmed a second affected dog from the litter and gave clinical suspicion of a third affected dog. Our sincere thanks to Prof. G. Mori for his efforts to set up the Italian HA mutation database. Without his help, this work would never have been accomplished.

This finding sparked a retrospective investigation of the clinical history of the male siblings. The dog was euthanized at the age of 9 months due to poor animal welfare after repeated severe intra-articular bleedings. Among the 384 different mutations detected, 217 (57%) have not previously been reported in the F8 HAMSTeRS mutation database.

Probability of high-risk genetic matching with oocyte and semen donors: complete gene analysis or genotyping test?

They include 105 missense mutations (48%), 41 small deletions (19%), 25 splice-site mutations (12%), 24 nonsense mutations (11%), 18 insertions (8%), three large deletions (1%), and one deletion + insertion . Unfortunately, we were not able to investigate mRNA of the affected males. But the description of SINE insertions as a genetic cause in other diseases is a strong argument for this SINE variant damaging the functionality of the FVIII protein. Both the altered splicing and the altered translation would lead to a protein with a mutated or missing light chain.


The two affected males showed the variant hemizygously, whereas the mother and four additional female puppies were heterozygotes. All unaffected males and five female siblings showed only the wildtype allele. Hence, the occurrence of the SINE variant in the family tree showed an inherence pattern typical of X-linked recessive traits. Additionally, this variant was not found in other unrelated dogs of the same breed or dogs of other breeds. Therefore, the SINE insertion is not a common finding, and therefore deemed clinically important. Our results enable genetic testing of Rhodesian Ridgebacks lines where Hemophilia A is suspicious because of affected male offspring in previous matings or relationship to the studied family.

It is present in the blood linked to von Willebrand factor in a non-covalent complex. In its activated form, FVIIIa acts as a cofactor for the prothrombinase complex in the intrinsic coagulation pathway by catalyzing activation of FX in the presence of FIXa . As the F8 gene lies on the X chromosome, hemophilia A is inherited in an X chromosomal recessive manner. Male dogs are phenotypically affected with just one mutated X chromosome while female dogs are heterozygous carriers passing the mutated allele to its offspring. Other breed-specific genetic variants causing Hemophilia A are later described in the breeds Old English Sheepdog , Boxer , German Shepherd , and Havanese .
