Special Issue Information

Dear Colleagues,

Wolfram syndrome 1 (WS1) is a rare neurodegenerative disease transmitted in an autosomal recessive mode. The main clinical features are diabetes insipidus (DI), diabetes mellitus (DM), optic atrophy (OA), and deafness (D), hence the acronym DIDMOAD. It is frequently complicated by other symptoms, such as urinary tract, endocrinological, psychiatric, and neurological abnormalities. Early onset nonautoimmune insulin-dependent DM and bilateral OA are key clinical criteria for the diagnosis of WS1. WS1 is caused by mutations in the WFS1 gene located on chromosome 4p16, which encodes a transmembrane protein named wolframin. Wolframin plays a key role in the regulation of ER calcium homeostasis and, therefore, in cellular apoptosis. More than 200 mutations are responsible for WS1.

Many patients exhibit abnormal phenotypes of WS with or without DM. In these cases, WFS1 mutations are inherited in an autosomal dominant mode. Furthermore, recessive Wolfram-like diseases without DM have been described.

Unfortunately, the prognosis of WS1 is poor, and death occurs prematurely. However, careful clinical monitoring during the rapid progression of the disease can be helpful to patients in improving their quality of life.

Currently, there are no therapies that can slow down or stop the clinical complications of WS1. However, many experimental studies have concentrated on the development of new therapies for WS1.

This Special Issue focuses on the molecular pathology of Wolfram syndrome 1 and explores potential treatment options from the perspective of genetics. For any of these topics, this Special Issue is open to contributions, in the form of both review and research articles.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Wolfram syndrome 1 (WS1) is a rare autosomal recessive neurodegenerative disease caused by mutations in WFS1 and WFS2 genes that produce wolframin, a protein involved in endoplasmic reticulum calcium homeostasis and cellular apoptosis. Its main clinical features are diabetes insipidus (DI), early-onset non-autoimmune insulin-dependent diabetes mellitus (DM), gradual loss of vision due to optic atrophy (OA) and deafness (D), hence the acronym DIDMOAD. Several other features from different systems have been reported such as urinary tract, neurological, and psychiatric abnormalities. In addition, endocrine disorders that can appear during childhood and adolescence include primary gonadal atrophy and hypergonadotropic hypogonadism in males and menstrual cycle abnormalities in females. Further, anterior pituitary dysfunction with deficient GH and/or ACTH production have been described. Despite the lack of specific treatment for the disease and its poor life expectancy, early diagnosis and supportive care is important for timely identifying and adequately managing its progressive symptoms. The current narrative review focuses on the pathophysiology and the clinical features of the disease, with a special emphasis on its endocrine abnormalities that appear during childhood and adolescence. Further, therapeutic interventions that have been proven to be effective in the management of WS1 endocrine complications are discussed. Full article
