Abstract
Objective To confirm diagnosis and explore the genetic aetiology in a Chinese patient
suspected to have Cockayne syndrome (CS). Methods The patient was clinically examined, and the patient and her biological
parents underwent genetic analysis using whole exome sequencing (WES) and
Sanger sequencing. The foetus of the patient’s mother underwent prenatal
diagnostic Sanger sequencing using amniotic fluid obtained at 19 weeks’
gestation. Results Clinical examination of the patient showed developmental delay, progressive
neurologic dysfunction and premature aging. Two compound, heterozygous ERCC
excision repair 6, chromatin remodelling factor (ERCC6)
gene mutations were detected in the proband by WES and confirmed by Sanger
sequencing, comprising a known paternal nonsense mutation (c.643G > T,
p.E215X) and a novel maternal short insertion and deletion mutation
(c.1614_c.1616delGACinsAAACGTCTT, p.K538_T539delinsKNVF). The patient was
consequently diagnosed with CS type I. The foetus of the patient’s mother
was found to carry only the maternally-derived
c.1614_c.1616delGACinsAAACGTCTT variant. Conclusion This study emphasized the value of WES in clinical diagnosis, and enriched
the known spectrum of ERCC6 gene mutations.

Abstract
Cockayne syndrome (CS) is one the rare DNA-repair deficiency disorders with autosomal recessive inheritance. Failure to thrive and microcephaly are the major criteria of diagnosis. Owing to genetic heterogeneity of CS, whole exome sequencing is promising way to determine the genetic basis of the disease. Here, we present c.1053delT in ERCC8 gene in an Iranian family with symptom of CS using whole exome sequencing. The deletion was novel and was not previously reported elsewhere.

Uncommon nucleotide excision repair phenotypes revealed by targeted high-throughput sequencing. Orphanet J Rare Dis 2016; 11:26.

Abstract
BACKGROUND Deficient nucleotide excision repair (NER) activity causes a variety of autosomal recessive diseases including xeroderma pigmentosum (XP) a disorder which pre-disposes to skin cancer, and the severe multisystem condition known as Cockayne syndrome (CS). In view of the clinical overlap between NER-related disorders, as well as the existence of multiple phenotypes and the numerous genes involved, we developed a new diagnostic approach based on the enrichment of 16 NER-related genes by multiplex amplification coupled with next-generation sequencing (NGS). METHODS Our test cohort consisted of 11 DNA samples, all with known mutations and/or non pathogenic SNPs in two of the tested genes. We then used the same technique to analyse samples from a prospective cohort of 40 patients. Multiplex amplification and sequencing were performed using AmpliSeq protocol on the Ion Torrent PGM (Life Technologies). RESULTS We identified causative mutations in 17 out of the 40 patients (43%). Four patients showed biallelic mutations in the ERCC6(CSB) gene, five in the ERCC8(CSA) gene: most of them had classical CS features but some had very mild and incomplete phenotypes. A small cohort of 4 unrelated classic XP patients from the Basque country (Northern Spain) revealed a common splicing mutation in POLH (XP-variant), demonstrating a new founder effect in this population. Interestingly, our results also found ERCC2(XPD), ERCC3(XPB) or ERCC5(XPG) mutations in two cases of UV-sensitive syndrome and in two cases with mixed XP/CS phenotypes. CONCLUSIONS Our study confirms that NGS is an efficient technique for the analysis of NER-related disorders on a molecular level. It is particularly useful for phenotypes with combined features or unusually mild symptoms. Targeted NGS used in conjunction with DNA repair functional tests and precise clinical evaluation permits rapid and cost-effective diagnosis in patients with NER-defects.
