Abstract
Werner's syndrome is a rare progressive disorder that is characterized by a variety of clinical manifestations which mimic features of advanced ageing. Malignancy is one of the most problematic complications of Werner's syndrome. Lung cancer associated with Werner's syndrome is rare. A 54-year-old woman with Werner's syndrome was referred to our department because an abnormal shadow had been detected on routine chest radiography. Chest computed tomography revealed an abnormal nodule in the left upper lobe. Bronchoscopic examination revealed the presence of squamous cell carcinoma. Other imaging studies showed no metastatic lesions; therefore, the patient was diagnosed with stage IA3 squamous cell carcinoma. She underwent left upper lobectomy and lymph node dissection without major complications, and no recurrence was found for 2 years postoperatively.

Abstract
James German's work to establish the natural history and cancer risk associated with Bloom syndrome (BS) has had a strong influence on the generation of scientists and clinicians working to understand other RECQ deficiencies and heritable cancer predisposition syndromes. I summarize work by us and others below, inspired by James German's precedents with BS, to understand and compare BS with the other heritable RECQ deficiency syndromes with a focus on Werner syndrome (WS). What we know, unanswered questions and new opportunities are discussed, as are potential ways to treat or modify WS-associated disease mechanisms and pathways.

Abstract
AIM Whether sex differences exist in hereditary progeroid syndromes remains unclear. In this study, we investigated sex differences in patients with Werner syndrome (WS), a model of human aging, using patient data at the time of diagnosis. METHODS The presence of six cardinal signs in the diagnostic criteria was retrospectively evaluated. RESULTS We found that the percentage of patients with all cardinal signs was higher in males than in females (54.2% vs. 21.2%). By the age of 40 years, 57.1% of male patients with WS presented with all the cardinal signs, whereas none of the female patients developed all of them. In particular, the frequency of having a high-pitched, hoarse voice, a characteristic of WS, was lower in female patients. The positive and negative predictive values for clinical diagnosis were 100% for males and females, indicating the helpfulness of diagnostic criteria regardless of sex. More female patients than male (86.7% vs. 64%) required genetic testing for their diagnosis because their clinical symptoms were insufficient, suggesting the importance of genetic testing for females even if they do not show typical symptoms of WS. Finally, the frequency of abnormal voice was lower in patients with WS harboring the c.3139-1G > C homozygous mutation. CONCLUSION These results indicate, for the first time, that there are sex differences in the phenotypes of hereditary progeroid syndromes. The analysis of this mechanism in this human model of aging may lead to the elucidation of sex differences in the various symptoms of normal human aging. Geriatr Gerontol Int 2024; 24: 161-167.

Abstract
Werner Syndrome is a rare autosomal recessive condition characterized by premature aging and increased risk of malignancies due to gene mutations associated with DNA stability. We present the first case report of a 29-year-old Hispanic female with WS diagnosed with breast cancer. Diagnostic mammography and ultrasound, breast MRI and PET examinations revealed two lesions biopsy proven as invasive ductal carcinoma. The patient underwent neoadjuvant chemotherapy and radical mastectomy. Recurrence occurred 10 months postoperatively with molecular analysis demonstrating TP53 mutations. The multifactorial assessment of breast cancer in this case study is crucial towards optimizing screening, diagnosis and management of this disease in patients with WS.

Abstract
Werner syndrome is an adult-onset progeria syndrome that results in various complications. This study aimed to clarify the profile and secular variation of the disease. Fifty-one patients were enrolled and registered in the Werner Syndrome Registry. Their data were collected annually following registration. A cross-sectional analysis at registration and a longitudinal analysis between the baseline and each subsequent year was performed. Pearson's chi-squared and Wilcoxon signed-rank tests were used. Malignant neoplasms were observed from the fifth decade of life (mean onset: 49.7 years) and were observed in approximately 30% of patients during the 3-year survey period. Regarding renal function, the mean estimated glomerular filtration rate calculated from serum creatinine (eGFRcre) and eGFRcys, which were calculated from cystatin C in the first year, were 98.3 and 83.2 mL/min/1.73 m2, respectively, and differed depending on the index used. In longitudinal analysis, the average eGFRcre for the first and fourth years was 74.8 and 63.4 mL/min/1.73 m2, showing a rapid decline. Secular changes in Werner syndrome in multiple patients were identified. The prevalence of malignant neoplasms is high, and renal function may decline rapidly. It is, therefore, necessary to carry out active and detailed examinations and pay attention to the type and dose of the drugs used.

Discovery of a new hereditary RECQ helicase disorder RECON syndrome positions the replication stress response and genome homeostasis as centrally important processes in aging and age-related disease. Ageing Res Rev 2023; 86:101887. [PMID: 36805074 PMCID: PMC10018417 DOI: 10.1016/j.arr.2023.101887] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 02/02/2023] [Accepted: 02/15/2023] [Indexed: 02/22/2023]
Abstract
Characterizing the molecular deficiencies underlying human aging has been a formidable challenge as it is clear that a complex myriad of factors including genetic mutations, environmental influences, and lifestyle choices influence the deterioration responsible for human pathologies. In addition, the common denominators of human aging, exemplified by the newly updated hallmarks of aging (López-Otín et al., 2023), suggest multiple avenues and layers of crosstalk between pathways important for genome and cellular homeostasis, both of which are major determinants of both good health and lifespan. In this regard, we postulate that hereditary disorders characterized by chromosomal instability offer a unique window of insight into aging and age-related disease processes. Recently, we discovered a new RECQ helicase disorder, designated RECON syndrome attributed to bi-allelic mutations in the RECQL1 gene (Abu-Libdeh et al., 2022). Cells deficient in RECQL1 exhibit genomic instability and a compromised response to replication stress, providing further evidence for the significance of genome homeostasis to suppress disease phenotypes. Here we provide a perspective on the pathology of RECON syndrome to inform the reader as to how molecular defects in the RECQL1 gene contribute to underlying deficiencies in nucleic acid metabolism often seen in certain aging or age-related diseases.

Abstract
Werner syndrome (WS), also known as adult progeria, is a premature ageing syndrome that can manifest itself with grey hair, hair loss, diabetes mellitus, hyperlipidaemia, hypertension, skin disorders, ocular cataracts, myocardial infarction, osteoporosis, and stroke, especially after puberty. Physical examination findings similar to systemic sclerosis may be seen. Therefore, it may mimic this disease as misleading. A 43-year-old female patient was admitted to our clinic with a pre-diagnosis of systemic sclerosis complaint of skin hardening up to the ankle. In the first physical examination, there were wrinkles and thinning of the lip, suggesting systemic sclerosis in the facial appearance. On her capillaroscopy, there was tortuosity and an old focus of microhemorrhage. She had a history of diabetes mellitus and chronic osteomyelitis. When all symptoms, clinical findings, and antibody results were combined, it was thought that the patient might have WS. WS was diagnosed with homozygous c.2221 C>P p.R741*(rs763089663) positive in genetic analysis. It is known that WS creates a predisposition to malignancies, and most patients die secondary to malignancies. Therefore, early diagnosis becomes essential. Early diagnosis is of vital importance both to prevent complications and to delay treatment. In particular, systemic sclerosis-like findings of this syndrome may cause delays in diagnosis. For this reason, small clues suggesting WS in the clinic should be well known and well defined.

Abstract
Werner syndrome (WS), also known as adult progeria, is a rare autosomal recessive inherited progeroid syndrome characterised by multiple features consistent with accelerated ageing. This disease is associated with several rheumatic conditions such as early osteoarthritis and osteoporosis, sarcopenia, soft-tissue calcifications, gout, limb ulcers and scleroderma-like skin features. WS should be included in the differential diagnosis of systemic sclerosis. The diagnosis is clinical, and in 90% of cases, a genetic test reveals a pathogenic variant of the WRN gene.WRN encodes a member of the RecQ family of DNA helicases and has a role in DNA repair. 86 different pathological WRN mutations have been identified so far. Here we present a case report of a typical WS patient associated with a newly described genetic variant of the WRN gene.
