The Werner syndrome (WS) is a rare autosomal recessive progeroid disorder. The Werner syndrome gene (WRN) has recently been identified as a member of the helicase family. Four distinct mutations were previously reported in three Japanese and one Syrian WS pedigrees. The latter mutation was originally described as a 4 bp deletion spanning a spliced junction. It is now shown that this mutation re...

Progeroid disorders overlapping with De Barsy syndrome (DBS) are collectively denoted as autosomal-recessive cutis laxa type 3 (ARCL3). They are caused by biallelic mutations in PYCR1 or ALDH18A1, encoding pyrroline-5-carboxylate reductase 1 and pyrroline-5-carboxylate synthase (P5CS), respectively, which both operate in the mitochondrial proline cycle. We report here on eight unrelated individ...

Ruijs-Aalfs syndrome is a segmental progeroid syndrome resulting from mutations in the SPRTN gene. Cells derived from patients with SPRTN mutations elicit genomic instability and people afflicted with this syndrome developed hepatocellular carcinoma. Here we describe the molecular mechanism by which SPRTN contributes to genome stability and normal cellular homeostasis. We show that SPRTN is a D...

Progeria is characterized by clinical features that mimic premature ageing. Although the mutation responsible for this syndrome has been deciphered, the mechanism of its action remains elusive. Progeria research has gained momentum particularly in the last two decades because of the possibility of revealing evidences about the ageing process in normal and other pathophysiological conditions. Va...

background and objective: preterm birth is a public health problem and late preterm birth (deliveries between 34-36 weeks of gestation) accounts for 75% of all preterm births. antenatal betamethasone can reduce the severity of respiratory distress in preterm infants and its effect is accepted in 24-34 weeks of gestation. our goal was to determine the neonatal outcomes of betamethasone prescript...

fanconi- bickel syndrome (fbs) is a rare type of glycogen storage disease (gsd) characterized by hepatomegaly, proximal renal tubular acidosis (rta) and marked growth retardation. we report a case of fbs presenting with diabetic ketoacidosis and transient neonatal diabetes. a female infant, product of consanguineous marriage presented with diabetic ketoacidosis at age 33 days, and was treated a...

conclusions mothers with sle should be screened and closely followed up during pregnancy for the development of fetal atrioventricular (av) block. case presentation a term infant with fetal bradycardia, detected at the 23rd gestational age, was diagnosed with chb due to nls and was successfully treated with a permanent epicardial pacemaker. the patient was reported here due to rarity of the pro...
