Wolfram syndrome: Portuguese research.

Area of Science:

• Genetics
• Endocrinology
• Neurology

Background:

• Wolfram syndrome (WFS), also known as DIDMOAD, is a rare autosomal recessive disorder.
• It primarily involves the Wolfram syndrome 1 gene (WFS1) and presents complex clinical features.
• Phenotypic variability and rarity complicate patient management.

Purpose of the Study:

• To describe the clinical characteristics and follow-up of 11 Wolfram syndrome patients.
• To analyze the presentation and progression of WFS in a tertiary hospital cohort.
• To identify common mutations in the WFS1 gene associated with the disorder.

Main Methods:

• Retrospective analysis of 11 WFS patients diagnosed between 1990 and 2020.
• Review of clinical data including diabetes mellitus, optic atrophy, diabetes insipidus, and deafness.
• Genetic analysis for mutations in the WFS1 gene.

Main Results:

• Nine patients presented with diabetes mellitus (DM), two with impaired glucose tolerance.
• All patients exhibited optic atrophy (OA); median diagnosis age was 14 years.
• Four patients had diabetes insipidus (DI), diagnosed in adolescence; hearing impairment, urological, neurological, and psychiatric disorders were also noted.

Conclusions:

• This study provides valuable clinical data on Wolfram syndrome.
• Understanding WFS1 mutations and clinical phenotypes is crucial for patient care.
• Further research can aid in developing improved prevention and management strategies for WFS.
