High frequency of exon 15 deletion in the FANCA gene in Tunisian patients affected with Fanconi anemia disease: implication for diagnosis. Mol Genet Genomic Med 2014; 2:160-5.

Abstract
Tunisian population is characterized by its heterogeneous ethnic background and high rate of consanguinity. In consequence, there is an increase in the frequency of recessive genetic disorders including Fanconi anemia (FA). The aim of this study was to confirm the existence of a founder haplotype among FA Tunisian patients and to identify the associated mutation in order to develop a simple tool for FA diagnosis. Seventy-four unrelated families with a total of 95 FA patients were investigated. All available family members were genotyped with four microsatellite markers flanking FANCA gene. Haplotype analysis and homozygosity mapping assigned 83 patients belonging to 62 families to the FA-A group. A common haplotype was shared by 42 patients from 26 families at a homozygous state while five patients from five families were heterozygous. Among them, 85% were from southern Tunisia suggesting a founder effect. Using multiplex ligation-dependent probe amplification (MLPA) technique, we have also demonstrated that this haplotype is associated with a total deletion of exon 15 in FANCA gene. Identification of a founder mutation allowed genetic counseling in relatives of these families, better bone marrow graft donor selection and prenatal diagnosis. This mutation should be investigated in priority for patients originating from North Africa and Middle East.

Abstract
Fanconi anemia (FA) is an inherited bone marrow failure syndrome associated with a progressive decline in hematopoietic stem cells, developmental defects, and predisposition to cancer. These various phenotypic features imply a role of FA proteins in molecular events regulating cellular homeostasis. Interestingly, we previously found that the Fanconi C protein (FANCC) interacts with the C-terminal-binding protein-1 (CtBP1) involved in transcriptional regulation. Here we report that FANCC with CtBP1 forms a complex with β-catenin, and that β-catenin activation through glycogen synthase kinase 3β inhibition leads to FANCC nuclear accumulation and FA pathway activation, as measured by the Fanconi D2 protein (FANCD2) monoubiquitination. β-catenin and FANCC nuclear entry is defective in FA mutant cells and in cells depleted of the Fanconi A protein or FANCD2, suggesting that integrity of the FA pathway is required for FANCC nuclear activity. We also report that FANCC with CtBP1 acts as a negative regulator of Dickkopf-1 (DKK1) expression, and that a FA disease-causing mutation in FANCC abrogates this function. Our findings reveal that a defective FA pathway leads to up-regulation of DKK1, a molecule involved in hematopoietic malignancies.

Mutation analysis of the ERCC4/FANCQ gene in hereditary breast cancer. PLoS One 2014; 9:e85334.

Abstract
The ERCC4 protein forms a structure-specific endonuclease involved in the DNA damage response. Different cancer syndromes such as a subtype of Xeroderma pigmentosum, XPF, and recently a subtype of Fanconi Anemia, FA-Q, have been attributed to biallelic ERCC4 gene mutations. To investigate whether monoallelic ERCC4 gene defects play some role in the inherited component of breast cancer susceptibility, we sequenced the whole ERCC4 coding region and flanking untranslated portions in a series of 101 Byelorussian and German breast cancer patients selected for familial disease (set 1, n = 63) or for the presence of the rs1800067 risk haplotype (set 2, n = 38). This study confirmed six known and one novel exonic variants, including four missense substitutions but no truncating mutation. Missense substitution p.R415Q (rs1800067), a previously postulated breast cancer susceptibility allele, was subsequently screened for in a total of 3,698 breast cancer cases and 2,868 controls from Germany, Belarus or Russia. The Gln415 allele appeared protective against breast cancer in the German series, with the strongest effect for ductal histology (OR 0.67; 95%CI 0.49; 0.92; p = 0.003), but this association was not confirmed in the other two series, with the combined analysis yielding an overall Mantel-Haenszel OR of 0.94 (95% CI 0.81; 1.08). There was no significant effect of p.R415Q on breast cancer survival in the German patient series. The other three detected ERCC4 missense mutations included two known rare variants as well as a novel substitution, p.E17V, that we identified on a p.R415Q haplotype background. The p.E17V mutation is predicted to be probably damaging but was present in just one heterozygous patient. We conclude that the contribution of ERCC4/FANCQ coding mutations to hereditary breast cancer in Central and Eastern Europe is likely to be small.

Abstract
RecQ family DNA helicases function in the maintenance of genome stability. Mice deficient in RecQL5, one of five RecQ helicases, show a cancer predisposition phenotype, suggesting that RecQL5 plays a tumor suppressor role. RecQL5 interacts with Rad51, a key factor in homologous recombination (HR), and displaces Rad51 from Rad51-single stranded DNA (ssDNA) filaments in vitro. However, the precise roles of RecQL5 in the cell remain elusive. Here, we present evidence suggesting that RecQL5 is involved in DNA interstrand crosslink (ICL) repair. Chicken DT40 RECQL5 gene knockout (KO) cells showed sensitivity to ICL-inducing agents such as cisplatin (CDDP) and mitomycin C (MMC) and a higher number of chromosome aberrations in the presence of MMC than wild-type cells. The phenotypes of RECQL5 KO cells resembled those of Fanconi anemia gene KO cells. Genetic analysis using corresponding gene knockout cells showed that RecQL5 is involved in the FANCD1 (BRCA2)-dependent ICL repair pathway in which Rad51-ssDNA filament formation is promoted by BRCA2. The disappearance but not appearance of Rad51-foci was delayed in RECQL5 KO cells after MMC treatment. Deletion of Rad54, which processes the Rad51-ssDNA filament in HR, in RECQL5 KO cells increased sensitivity to CDDP and further delayed the disappearance of Rad51-foci, suggesting that RecQL5 and Rad54 have different effects on the Rad51-ssDNA filament. Furthermore, the frequency and variation of CDDP-induced gene conversion at the immunoglobulin locus were increased in RECQL5 KO cells. These results suggest that RecQL5 plays a role in regulating the incidence and quality of ICL-induced recombination.

Abstract
The inherited bone marrow failure (BMF) syndromes are a rare and diverse group of genetic disorders that ultimately result in the loss of blood production. The molecular defects underlying many of these conditions have been elucidated, and great progress has been made toward understanding the normal function of these gene products. This review will focus on perhaps the most well-known and genetically heterogeneous BMF syndrome: Fanconi anemia. More specifically, this account will review the current state of our knowledge on why the bone marrow fails in this illness and what this might tell us about the maintenance of bone marrow function and hematopoiesis.

Abstract
The unscheduled DNA synthesis (UDS) assay measures the ability of a cell to perform global genomic nucleotide excision repair (NER). This chapter provides instructions for the application of this technique by creating 6-4 photoproducts and pyrimidine dimers using UV-C irradiation. This procedure is designed specifically for quantification of the 6-4 photoproducts. Repair is quantified by the amount of radioactive thymidine incorporated during repair synthesis after this insult, and radioactivity is evaluated by grain counting after autoradiography. The results are used to clinically diagnose human DNA repair deficiency disorders and provide a basis for investigation of repair deficiency in human tissues or tumors. No other functional assay is available that directly measures the capacity to perform NER on the entire genome without the use of specific antibodies. Since live cells are required for this assay, explant culture techniques must be previously established. Host cell reactivation (HCR), as discussed in Chapter 37, is not an equivalent technique, as it measures only transcription-coupled repair (TCR) at active genes, a small subset of total NER.

Abstract
Nucleotide excision repair (NER) is critical for the repair of DNA lesions induced by UV radiation, but its contribution in replicating cells is less clear. Here, we show that dual incision by NER endonucleases, including XPF and XPG, promotes the S-phase accumulation of the BRCA1 and Fanconi anemia-associated DNA helicase FANCJ to sites of UV-induced damage. FANCJ promotes replication protein A phosphorylation and the arrest of DNA synthesis following UV irradiation. Interaction defective mutants of FANCJ reveal that BRCA1 binding is not required for FANCJ localization, whereas interaction with the mismatch repair (MMR) protein MLH1 is essential. Correspondingly, we find that FANCJ, its direct interaction with MLH1, and the MMR protein MSH2 function in a common pathway in response to UV irradiation. FANCJ-deficient cells are not sensitive to killing by UV irradiation, yet we find that DNA mutations are significantly enhanced. Thus, we considered that FANCJ deficiency could be associated with skin cancer. Along these lines, in melanoma we found several somatic mutations in FANCJ, some of which were previously identified in hereditary breast cancer and Fanconi anemia. Given that, mutations in XPF can also lead to Fanconi anemia, we propose collaborations between Fanconi anemia, NER, and MMR are necessary to initiate checkpoint activation in replicating human cells to limit genomic instability.

Abstract
Fanconi anemia (FA) is a rare recessive disease, characterized by congenital defects, bone marrow failure, and increased cancer susceptibility. FA is caused by biallelic mutation of any one of sixteen genes. The protein products of these genes function cooperatively in the FA-BRCA pathway to repair DNA interstrand crosslinks (ICLs). A central step in the activation of this pathway is the monoubiquitination of the FANCD2 and FANCI proteins. Monoubiquitinated FANCD2 and FANCI localize to discrete chromatin regions where they function in ICL repair. Despite their critical role in ICL repair, very little is known about the structure, function, and regulation of the FANCD2 and FANCI proteins, or how they are targeted to the nucleus and chromatin. In this study, we describe the functional characterization of an amino-terminal FANCD2 nuclear localization signal (NLS). We demonstrate that the amino terminal 58 amino acids of FANCD2 can promote the nuclear expression of GFP and is necessary for the nuclear localization of FANCD2. Importantly, mutation of this FANCD2 NLS reveals that intact FANCD2 is required for the nuclear localization of a subset of FANCI. In addition, the NLS is necessary for the efficient monoubiquitination of FANCD2 and FANCI and, consequently, for their localization to chromatin. As a result, FANCD2 NLS mutants fail to rescue the ICL sensitivity of FA-D2 patient cells. Our studies yield important insight into the domain structure of the poorly characterized FANCD2 protein, and reveal a previously unknown mechanism for the coordinate nuclear import of a subset of FANCD2 and FANCI, a key early step in the cellular ICL response.

Abstract
DNA interstrand cross-links (ICLs) are lesions caused by a variety of endogenous metabolites, environmental exposures, and cancer chemotherapeutic agents that have two reactive groups. The common feature of these diverse lesions is that two nucleotides on opposite strands are covalently joined. ICLs prevent the separation of two DNA strands and therefore essential cellular processes including DNA replication and transcription. ICLs are mainly detected in S phase when a replication fork stalls at an ICL. Damage signaling and repair of ICLs are promoted by the Fanconi anemia pathway and numerous posttranslational modifications of DNA repair and chromatin structural proteins. ICLs are also detected and repaired in nonreplicating cells, although the mechanism is less clear. A unique feature of ICL repair is that both strands of DNA must be incised to completely remove the lesion. This is accomplished in sequential steps to prevent creating multiple double-strand breaks. Unhooking of an ICL from one strand is followed by translesion synthesis to fill the gap and create an intact duplex DNA, harboring a remnant of the ICL. Removal of the lesion from the second strand is likely accomplished by nucleotide excision repair. Inadequate repair of ICLs is particularly detrimental to rapidly dividing cells, explaining the bone marrow failure characteristic of Fanconi anemia and why cross-linking agents are efficacious in cancer therapy. Herein, recent advances in our understanding of ICLs and the biological responses they trigger are discussed.

Abstract
STUDY OBJECTIVE Differences between men and women in management and outcome following cerebrovascular events have been described. However, most of the differences observed have only been partially adjusted for baseline differences, or not at all. The objective of the present study was to compare acute and follow-up management between men and women after stroke and transitory ischemic attacks, adjusting for potential confounders. DESIGN Patients with symptoms of stroke were included at admission to one of four participating hospitals in the inner city of Berlin, Germany. Risk factors, clinical characteristics, and acute management were assessed from medical records. Patients were asked about socioeconomic factors and follow-up management in a baseline interview and by postal questionnaire, respectively. The follow-up was 12 months. Multiple logistic regression analyses were used to assess odds ratios for management variables. RESULTS A total of 558 patients were included (55% men, mean age 65+/-13 years; 45% women, 69+/-14 years). Indications for admission were stroke (74%) and transitory ischemic attacks (26%). In multivariable analyses, there were no differences in diagnostic procedures performed at baseline and in follow-up management between men and women. However, women were significantly more likely to receive hypoglycemic drugs (odds ratio 2.49; 95% confidence interval 1.33-4.63) in the acute management period. Regarding the need for nursing support/a nursing home after 12 months, there were no significant differences between men and women. CONCLUSIONS After adjustment for differences in baseline characteristics, we only found few differences in acute and long-term management between men and women following hospital admission after suffering a cerebrovascular event.
