The RECQL4 helicase gene is a member of the RECQL gene family, mutated in some Rothmund-Thomson syndrome (RTS) patients. Other members of this gene family are BLM mutated in Bloom syndrome, WRN mutated in Werner syndrome and RECQL and RECQL5. All polypeptides encoded by RECQL genes share a central region of seven helicase domains. The function of RECQL4 remains unknown, but based on the domain ...

PURPOSE Werner syndrome is an autosomal recessive disease of premature aging caused by a polymorphic C1367T mutation in the Werner (WRN) gene. Although there are differences between the pathobiology of normal aging and the phenotype of Werner syndrome, the clinical age-related changes are similar. The aim of the study was to investigate the incidence of the C1367T (rs1346044) polymorphism in pa...

We present this case of uterus didelphys with right sided haematometrocolpos due to obstructed hemivaginaand ipsilateral renal agenesis-Herlyn Werner Wunderlich syndrome. The condition was missed on ultrasoundand diagnosed plain CT scan abdomen and pelvis. This syndrome should be kept in mind while dealing witha young female complaining lower abdominal pain a pelvic mass having unilateral agene...

Werner syndrome (WS) is an autosomal recessive disease characterized by premature aging. Malignant tumors such as thyroid carcinoma and malignant melanoma occur frequently in WS patients. We describe 2 siblings with WS who suffered from sinonasal malignant melanoma (MM). Both patients initially experienced nasal obstruction and recurrent nasal bleeding and died within 2 years of the diagnosis o...

Progeroid syndromes, one of which is metageria, are characterized by signs of premature aging with multiple systemic and skin symptoms. Here we describe an 8-year-old girl with no historyof specific underlying disease in her family, no hair growth at the scalp since she was born, and taller and thinner than her peers. We noticed diffuse subcutaneous fat atrophy. The patientwas refer...

Two Iranian cases with very rare progeroid syndrome are reported. The first is a 24-year-old girl who has been healthy till her 13th birthday. From that time she has been suffering from a progressive generalized and multi-systemic illness. The cardinal clinical findings were growth retardation, subcutaneous fat loss, skin dryness and wrinkling, scattered focal sclerodermoid-like changes, promin...
