Publication: Nature.com | Publication Date: March 16, 2020

Authors: Chiara La Morgia, Alessandra Maresca, Giulia Amore, Laura Ludovica Gramegna, Michele Carbonelli, Emanuela Scimonelli, Alberto Danese, Simone Patergnani, Leonardo Caporali, Francesca Tagliavini, Valentina Del Dotto, Mariantonietta Capristo, Federico Sadun, Piero Barboni, Giacomo Savini, Stefania Evangelisti, Claudio Bianchini, Maria Lucia Valentino, Rocco Liguori, Caterina Tonon, Carlotta Giorgi, Paolo Pinton, Raffaele Lodi & Valerio Carelli

Abstract

Wolfram syndrome (WS) is a recessive multisystem disorder defined by the association of diabetes mellitus and optic atrophy, reminiscent of mitochondrial diseases. The role played by mitochondria remains elusive, with contradictory results on the occurrence of mitochondrial dysfunction. Read more

High Prevalence of a Monogenic Cause in Han Chinese Diagnosed With Type 1 Diabetes, Partly Driven by Nonsyndromic Recessive WFS1 Mutations

Publication: American Diabetes Association | Publication Date: January 2020

Authors: Meihang Li, Sihua Wang, Kuanfeng Xu, Yang Chen, Qi Fu, Yong Gu, Yun Shi, Mei Zhang, Min Sun, Heng Chen, Xiuqun Han, Yangxi Li, Zhoukai Tang, Lejing Cai, Zhiqiang Li, Yongyong Shi, Tao Yang and Constantin Polychronakos

Abstract

It is estimated that ∼1% of European ancestry patients clinically diagnosed with type 1 diabetes (T1D) actually have monogenic forms of the disease. Because of the much lower incidence of true T1D in East Asians, we hypothesized that the percentage would be much higher. Read more

Clinical and genetic analysis of two wolfram syndrome families with high occurrence of wolfram syndrome and diabetes type II: a case report

Publication: BMC Medical Genetics | Publication Date: January 14, 2020

Authors: Maryam Sobhani, Mohammad Amin Tabatabaiefar, Soudeh Ghafouri-Fard, Asadollah Rajab, Asal Hojjat, Abdol-Mohammad Kajbafzadeh & Mohammad Reza Noori-Daloii

Abstract

Conclusions: The mutational and phenotypic spectrum of WS is broadened by our report of novel WFS1 mutation. Our results reveal the value of molecular analysis of WFS1 in the improvement of clinical diagnostics for WS. Read more
