• W4382025414 abstract "Abstract A 27-year-old woman of Pakistani heritage with a background of type 2 diabetes, hypertension, hypothyroidism, infertility and Achilles tendinopathy was referred to the dermatology department for diffuse hair loss. She had greying of the scalp hair from the age of 20 years and, on examination, there were signs of hair fragility and thinning. Biopsies showed female pattern hair loss. Topical minoxidil 5% twice daily was advised. At the consultation, it was noted that her facial features included a thin nose with micrognathia. She had dental implants and had undergone cataract surgery at 19 years of age. Scleroderma-like changes were noted on the face and over the distal joints, alongside axillary freckling and excessive lentigines for her age and skin type. She was of short stature and low weight, with a body mass index (BMI) of 15.4 kg m–2. There was thenar and hypothenar wasting and loss of gluteal fat. Her parents were consanguineous (first cousins). One of her brothers, who had similar facial features, died aged 30 years from osteosarcoma. The patient and her partner had undergone two unsuccessful cycles of in vitro fertilization following 5 years of failure to conceive naturally. Medication consisted of atorvastatin, Calcichew, levothyroxine, lisinopril, metformin, pioglitazone and repaglinide. Routine bloods and hormone profile were normal. Despite her age, BMI and statin treatment, blood lipids were raised and a liver ultrasound showed fatty changes. The dermatology department queried Werner syndrome and referral to a tertiary lipodystrophy clinic was made. The lipodystrophy genetic panel was completed. Homozygous null mutation at the WRN locus was found confirming a diagnosis of Werner syndrome. Werner syndrome is an extremely rare autosomal recessive form of progeroid syndrome first described by Otto Werner in 1904. The hallmark sign is the striking disproportion between the patient’s age and appearance. WRN encodes the eponymous WRN protein, a member of the RecQ-like DNA helicase family. The prognosis is unfavourable, with a mean survival of 54 years. Primary causes of mortality are cardiovascular disease and malignancy, with melanoma, thyroid cancer, osteosarcoma and soft tissue sarcoma being the most common forms. There is currently no specific treatment. Management is close multidisciplinary monitoring and treatment of associated conditions. A 2010 study of the Werner syndrome mouse model found vitamin C supplementation to be beneficial (Massip L, Garand C, Paquet ER et al. Vitamin C restores healthy aging in a mouse model for Werner syndrome. FASEB J 2010; 24:158–72). As the condition results in excess damage on ultraviolet exposure and a high risk of melanoma, as well as nonmelanoma skin cancers, an annual dermatology skin check is required." @default.
