Determined by the type of XPD mutation, six different clinical entities have been distinguished: XP, XP with neurological symptoms, trichothiodystrophy (TTD), XP/TTD complex, XP/Cockayne syndrome (CS) complex or the cerebro-oculo-facio-skeletal syndrome (COFS). We identified nine new XPD-deficient patients. Their fibroblasts showed reduced post-UV cell survival, reduced NER capacity, normal XPD mRNA expression and partly reduced XPD protein expression. Six patients exhibited a XP phenotype in accordance with established XP-causing mutations (c.2079G>A, p.R683Q; c.2078G>T, p.R683W; c.1833G>T, p.R601L; c.1878G>C, p.R616P; c.1878G>A, p.R616Q). One TTD patient was homozygous for the known TTD-causing mutation p.R722W (c.2195C>T). Two patients were compound heterozygous for a TTD-causing mutation (c.366G>A, p.R112H) and a novel p.D681H (c.2072G>C) amino acid exchange, but exhibited different TTD and XP/CS complex phenotypes, respectively. Interestingly, the XP/CS patient's cells exhibited a reduced but well detectable XPD protein expression compared with hardly detectable XPD expression of the TTD patient's cells. Same mutations with different clinical outcomes in NER-defective patients demonstrate the complexity of phenotype-genotype correlations, for example relating to additional genetic variations (parental consanguinity), different allelic expression due to SNPs or differences in the methylation status."],["dc.identifier.doi","10.1111/exd.12166"],["dc.identifier.isi","000320935600012"],["dc.identifier.pmid","23800062"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/29540"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell"],["dc.relation.issn","1600-0625"],["dc.relation.issn","0906-6705"],["dc.title","Functional and molecular genetic analyses of nine newly identified XPD-deficient patients reveal a novel mutation resulting in TTD as well as in XP/CS complex phenotypes"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

The current hypothesis is that missense mutations impair repair (xeroderma pigmentosum (XP) symptoms), whereas truncating mutations impair both repair and transcription (XP and Cockayne syndrome (CS) symptoms). We identified three cell lines of XPG-defective patients (XP40GO, XP72MA, and XP165MA). Patients' fibroblasts showed a reduced post-UVC cell survival. The reduced repair capability, assessed by host cell reactivation, could be complemented by XPG cDNA. XPG mRNA expression of XP165MA, XP72MA, and XP40GO was 83%, 97%, and 82.5%, respectively, compared with normal fibroblasts. XP165MA was homozygous for a p.G805R mutation; XP72MA and XP40GO were both compound heterozygous (p.W814S and p.E727X, and p.L778P and p.Q150X, respectively). Allele-specific complementation analysis of these five mutations revealed that p.L778P and p.W814S retained considerable residual repair activity. In line with the severe XP/CS phenotypes of XP72MA and XP165MA, even the missense mutations failed to interact with the transcription factor IIH subunits XPD and to some extent cdk7 in coimmunoprecipitation assays. Immunofluorescence techniques revealed that the mutations destabilized early recruitment of XP proteins to localized photodamage and delayed their redistribution in vivo. Thus, we identified three XPG missense mutations in the I-region of XPG that impaired repair and transcription and resulted in severe XP/CS."],["dc.identifier.doi","10.1038/jid.2013.54"],["dc.identifier.isi","000320428400023"],["dc.identifier.pmid","23370536"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/29576"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Nature Publishing Group"],["dc.relation.issn","1523-1747"],["dc.relation.issn","0022-202X"],["dc.title","Characterization of Three XPG-Defective Patients Identifies Three Missense Mutations that Impair Repair and Transcription"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Complementation group C (XP-C) is the most frequent group of XP patients worldwide. MethodsWe analyzed seven XP-C patients clinically and molecular-genetically applying: post-UV cell survival (MTT-assay), quantitative Real-time PCR, sequencing on chromosomal as well as cDNA level, and in silico interpretation of sequencing data. ResultsAll cases displayed diminished post-UV cell survival as well as reduced XPCmRNA levels. Five homozygous and two heterozygous disease causing mutations were identified. A large chromosomal deletion of similar to 5.8 kb identified in XP174MA leads to an unique in frame deletion of XPC exon 2 and exon 3. In silico analysis revealed the deletion of 102 amino acids in the N-terminal part of XPC while leaving the C-terminal domain intact. The novel c.361delA mutation in XP168MA leads to a frameshift in exon 3 resulting in a premature stop codon 27 codons downstream of the deleted adenine. ConclusionOur analysis confirms that XP-C patients without increased sun sensitivity develop non-melanoma skin cancers earlier than sun-sensitive XP-C patients. Reduced cellular mRNA levels are characteristic for XP complementation group C and qRT-PCR represents a rapid diagnostic tool."],["dc.identifier.doi","10.1111/phpp.12251"],["dc.identifier.isi","000388315900006"],["dc.identifier.pmid","27387384"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/39567"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell"],["dc.relation.issn","1600-0781"],["dc.relation.issn","0905-4383"],["dc.title","A unique chromosomal in-frame deletion identified among seven XP-C patients"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
