Diagnosis GeneReviews | Cockayne syndrome (CS) is characterized by growth failure and multisystemic degeneration, with a variable age of onset and rate of progression. The phenotypic spectrum of CS can be divided into three general clinical presentations: ... Gene Symbol% of CS Attributed to Mutations in This GeneTest MethodMutations DetectedTest AvailabilityERCC8~35% | Sequence analysisSequence variants 1, 2, 3ClinicalDeletion / duplication analysis 4Exonic or whole-gene deletions 2, 5ERCC6~65% Sequence analysisSequence variants 1, 2, 3ClinicalDeletion / duplication analysis 4Exonic or whole-gene deletions 2, 51. Mutations detected by sequence analysis may include small intragenic deletions/insertions and missense, nonsense, and splice site mutations; typically, exonic or whole-gene deletions/duplications are not detected.2. Pathologic allelic variants reported in ERCC8 and ERCC6 are summarized in Table 2.3. A majority are nonsense or frameshift mutations that predict a truncated protein [Troelstra et al 1992, Mallery et al 1998, Colella et al 1999, Meira et al 2000, Horibata et al 2004].4. Testing that identifies deletions/duplications not readily detectable by sequence analysis of the coding and flanking intronic regions of genomic DNA; included in the variety of methods that may be used are: quantitative PCR, long-range PCR, multiplex ligation-dependent probe amplification (MLPA), and chromosomal microarray (CMA) that includes this gene/chromosome segment.5. Exonic or whole gene deletions of ERCC8 escape detection by sequence analysis when present in a heterozygous state or compound heterozygous state [Henning et al 1995, Ren et al 2003, Cao et al 2004].Interpretation of test results. For issues to consider in interpretation of sequence analysis results, click here.Testing Strategy To establish the diagnosis in a proband involves molecular genetic testing 1Sequence analysis of ERCC6, followed by deletion/duplication analysis. If no ERCC6 mutation is identified, sequence analysis of ERCC8, followed by deletion/duplication analysis
Clinical Description GeneReviews | Before the molecular genetics of Cockayne syndrome was understood, it was thought to have a single, discrete phenotype: classic Cockayne syndrome. It is now recognized that Cockayne syndrome spans a phenotypic spectrum that includes the following [Nance & Berry 1992]: ... |
Genotype-Phenotype Correlations GeneReviews | There is no correlation between the biochemical defect in UV-mediated DNA repair assays and the clinical severity of the syndrome. The ability to repair oxidative lesions may distinguish individuals with UVSS from those with CS [Nardo et al 2009]... |
Differential Diagnosis GeneReviews | The differential diagnosis of CS depends on the presenting features of the particular individual. Abnormalities that suggest alternative diagnoses include congenital anomalies of the face, limbs, heart, or viscera; recurrent infections (other than otitis media or respiratory infections); metabolic or neurologic crises; hematologic abnormality (e.g., anemia, leukopenia); and cancer of any kind [Nance & Berry 1992].... |
Management GeneReviews | To establish the extent of disease in an individual diagnosed with Cockayne syndrome (CS), the following evaluations are recommended:... |
