Background: Dual-specificity tyrosine phosphorylation-regulated kinase 1B (DYRK1B) is a nutrient-sensing protein that suppresses the RAS–RAF–MEK pathway and is known to have a role in glucose uptake and glycolysis. The expression of DYRK1B increases during adipogenic differentiation suggesting an important role in adipogenesis. Mutations in DYRK1B have been described in three Iranian families and five Caucasian patients w...

Background: Obesity is highly prevalent worldwide, particularly in the MENA region. Whilst simple obesity has a variable genetic and environmental basis, syndromic and non-syndromic monogenic obesity has a strong genetic component. Melanocortin 4 receptor (MC4R) mutations are the commonest cause of monogenic obesity. MC4R also regulates neuropathic pain pathways via JNK signaling after nerve injury.Methods: Five children...
