Abstract
BACKGROUND Wolfram syndrome is a rare autosomal recessive neurodegenerative disorder that affects 1/200,000 to 1/1,000,000 children. It is characterized by juvenile onset diabetes, optic nerve atrophy and other systemic manifestations. Symptoms of the disease arise mostly in early childhood with a high mortality rate due to severe neurological complications. Two causative genes have been identifed in this syndrome; the classical form is caused by autosomal recessive mutations of the WFS1 gene, and a smaller portion of patients has mutations in the CIDS2 gene, which are responsible for autosomal recessive Wolfram syndrome 2. CASE PRESENTATION We report the case of a 28-year-old Moroccan boy born from consanguineous parents referred to the department of medical genetics at the National Institute of Health in Rabat. The diagnosis of Wolfram syndrome was made based on insulin-dependent diabetes, optic nerve atrophy, sensorineural deafness, urological abnormalities and psychiatric illness. To establish the diagnosis at a molecular level, we performed next-generation sequencing in the index patient, which revealed compound heterozygous WFS1 mutations: c.1113G > A (p.Trp371Ter) and c.1223_1224insGGAACCACCTGGAGCCCTATGCCCATTT (p.Phe408fs). This second variant has never been described in patients with Wolfram syndrome. CONCLUSION The identification of the genetic substrate in our patient confirmed the clinical diagnosis of Wolfram syndrome and allowed us to provide him an appropriate management and genetic counseling to his family.

Abstract
Wolfram syndrome (WS) is a rare neurodegenerative disease usually of autosomal recessive origin. There is limited research about sensorineural hearing loss, despite it being a fundamental entity. It is important to broaden the study of this disease and specify a set of tests required for an adequate assessment of patients for efficient monitoring and control. The fundamental objective of this research is to understand WS from a biomedical perspective in order to help in its diagnosis, follow-up, and control. Pure tones audiometry, tympanometry, speech perception, the speech intelligibility index without aid, and testing at high frequencies were among the audiological measurements utilised since they were deemed suitable for standardised follow-up. Mixed linear models were used to examine the effects of age, time, or mean interaction in pure-tone (IPT), the average of high frequencies (HFA), auditory brainstem response (ABR), and brainstem auditory evoked potentials (BAEP). The genetic analysis allowed mutations to be classified into three phenotype-genotype groups, where the phenotype indicated the severity of the hearing loss. Patients with homozygous gene changes had a more severe neurosensory phenotype. The early discovery of sensorineural hearing loss and WS is crucial since it allows intensive follow-up and treatment of the person affected from the start.

Abstract
Aims Wolfram Syndrome Spectrum Disorder (WFS1-SD), in its "classic" form, is a rare autosomal recessive disease with poor prognosis and wide phenotypic spectrum. Insulin dependent diabetes mellitus (DM), optic atrophy (OA) diabetes insipidus (DI) and sensorineural deafness (D) are the main features of WFS1-SD. Gonadal dysfunction (GD) has been described mainly in adults with variable prevalence and referred to as a minor clinical feature. This is the first case series investigating gonadal function in a small cohort of paediatric patients affected by WFS1-SD. Methods Gonadal function was investigated in eight patients (3 male and 5 female) between 3 and 16 years of age. Seven patients have been diagnosed with classic WFS1-SD and one with non-classic WFS1-SD. Gonadotropin and sex hormone levels were monitored, as well as markers of gonadal reserve (inhibin-B and anti-Mullerian hormone). Pubertal progression was assessed according to Tanner staging. Results Primary hypogonadism was diagnosed in 50% of patients (n=4), more specifically 67% (n=2) of males and 40% of females (n=2). Pubertal delay was observed in one female patient. These data confirm that gonadal dysfunction may be a frequent and underdiagnosed clinical feature in WFS1-SD. Conclusions GD may represent a frequent and earlier than previously described feature in WFS1-SD with repercussions on morbidity and quality of life. Consequently, we suggest that GD should be included amongst clinical diagnostic criteria for WFS1-SD, as has already been proposed for urinary dysfunction. Considering the heterogeneous and elusive presentation of WFS1-SD, this clinical feature may assist in an earlier diagnosis and timely follow-up and care of treatable associated diseases (i.e. insulin and sex hormone replacement) in these young patients.

Abstract
BACKGROUND Wolfram syndrome type 1 is a rare neurodegenerative disorder including diabetes insipidus, diabetes mellitus, optic atrophy, and deafness, with variable additional findings. The phenotypic spectrum is very heterogeneous, with non-autoimmune juvenile-onset diabetes and optic atrophy as minimal criteria for the diagnosis. Biallelic mutations in the WFS1 gene are the causative genetic anomaly for the syndrome, with, however, no evident genotype-phenotype correlation. Among the clinical features of the disease, diabetic retinopathy depicts a rarely reported microvascular complication. In this report, we describe the clinical and genetic findings in a 26-year-old patient presenting with Wolfram syndrome and severe diabetic retinopathy. METHODS The mutation screening was performed by polymerase chain reaction followed by Sanger sequencing of the entire coding sequence of the WFS1 gene. RESULTS A novel homozygous missense variant c.1901A>T (p.Lys634Met) was found in the proband and classified as probably pathogenic according to the American College of Medical Genetics and Genomics. CONCLUSIONS The molecular study of the WFS1 gene is essential for the diagnostic confirmation, to provide appropriate genetic counseling and a mutational screening in the at-risk relatives. The c.1901A>T (p.Lys634 Met) is a novel variant that could be responsible for a severe form of Wolfram syndrome with early and proliferative diabetic retinopathy.

Abstract
Las enfermedades raras, pese a su baja frecuencia individual, afectan globalmente al 7% de la población, por lo que el profesional de Atención Primaria (AP) tendrá varios de estos pacientes bajo seguimiento. El 80% de estas enfermedades tienen base genética, lo que hace fundamental un asesoramiento genético adecuado. El seguimiento de pacientes con síndrome de Wolfram (SW) puede servir para diseñar un protocolo susceptible de ser utilizado en el diagnóstico y manejo de otras entidades y ser utilizado por profesionales sanitarios para dar soporte a los pacientes, contando con la participación de profesionales sanitarios e investigadores especializados en el SW, los propios pacientes y su entorno. Se desarrollan los pasos fundamentales de todo procedimiento clínico genético, en el que la AP es clave para dar soporte a estas familias y transmitir de forma comprensible la información sobre los aspectos genéticos.

Abstract
PURPOSE To describe the clinical phenotype of a cohort of Wolfram syndrome (WS) patients, focusing on the pattern of optic atrophy correlated with brain MRI measurements, as compared to OPA1-associated mitochondrial optic neuropathy. DESIGN Retrospective, comparative cohort study METHODS: 25 WS patients and 33 age-matched patients affected by OPA1-related Dominant Optic Atrophy (DOA). Ophthalmological, neurological, endocrinological and MRI data from WS patients were retrospectively retrieved. Ophthalmological data were compared to OPA1-related DOA and further analyzed for age dependency dividing patients in age quartiles. In a subgroup of WS patients, we correlated the structural damage assessed by optical coherence tomography (OCT) with brain MRI morphological measurements. Visual acuity (VA), visual field mean defect (MD), retinal nerve fiber layer (RNFL) and ganglion cell layer (GCL) thickness assessed by OCT, MRI morphological measurements of anterior and posterior visual pathways. RESULTS In our cohort optic atrophy was present in 100% of WS patients. VA, MD and RNFL thickness loss were worse in WS patients with a faster decline since early age as compared to DOA patients, who displayed a more stable visual function over the years. Conversely, GCL sectors were overall thinner in DOA patients since early age compared to WS, in which GCL thickness started to decline later in life. The neuroradiological sub-analysis on 11 WS patients exhibited bilateral thinning of the anterior optic pathway, especially prechiasmatic optic nerves and optic tracts. Optic tract thinning was significantly correlated with the GCL thickness but not with RNFL parameters. CONCLUSIONS Our results showed a generally more severe and diffuse degeneration of both anterior and posterior visual pathways in WS, with fast deterioration of visual function and structural OCT parameters since early age. The pattern observed at OCT suggests that retinal ganglion cells axonal degeneration (i.e. RNFL) precedes of about a decade the cellular body atrophy (i.e. GCL). This differs substantially from DOA, in which a more stable visual function is evident with predominant early loss of GCL, indirectly supporting the lack of a primary mitochondrial dysfunction in WS.

Abstract
Wolfram syndrome (WS), also known as a DIDMOAD (diabetes insipidus, early-onset diabetes mellitus, optic nerve atrophy and deafness) is a rare autosomal disorder caused by mutations in the Wolframin1 (WFS1) gene. Previous studies have revealed that glucagon-like peptide-1 receptor agonist (GLP1 RA) are effective in delaying and restoring blood glucose control in WS animal models and patients. The GLP1 RA liraglutide has also been shown to have neuroprotective properties in aged WS rats. WS is an early-onset, chronic condition. Therefore, early diagnosis and lifelong pharmacological treatment is the best solution to control disease progression. Hence, the aim of this study was to evaluate the efficacy of the long-term liraglutide treatment on the progression of WS symptoms. For this purpose, 2-month-old WS rats were treated with liraglutide up to the age of 18 months and changes in diabetes markers, visual acuity, and hearing sensitivity were monitored over the course of the treatment period. We found that treatment with liraglutide delayed the onset of diabetes and protected against vision loss in a rat model of WS. Therefore, early diagnosis and prophylactic treatment with the liraglutide may also prove to be a promising treatment option for WS patients by increasing the quality of life.

Abstract
Monogenic diabetes mellitus, which is diabetes caused by a defect in a single gene that is associated with β cell function or insulin action, accounts for 1% to 6% of all pediatric diabetes cases. Accurate diagnosis is important, as the effective treatment differs according to genetic etiology in some types of monogenic diabetes: high-dose sulfonylurea treatment in neonatal diabetes caused by activating mutations in KCNJ11 or ABCC8; low-dose sulfonylurea treatment in HNF1A/HNF4A-diabetes; and no treatment in GCK diabetes. Monogenic diabetes should be suspected by clinicians for certain combinations of clinical features and laboratory results, and approximately 80% of monogenic diabetes cases are misdiagnosed as type 1 diabetes or type 2 diabetes. Here, we outline the types of monogenic diabetes and the clinical implications of genetic diagnosis.

Abstract
Neonatal diabetes (ND) appears during the first months of life and is caused by a single gene mutation. It is heterogenous and very different compared to other forms of multi-factorial or polygenic diabetes. Clinically, this form is extremely severe, however, early genetic diagnosis is pivotal for successful therapy. A large palette of genes is demonstrated to be a cause of ND, however, the mechanisms of permanent hyperglycemia are different. This review will give an overview of more frequent genetic mutations causing ND, including the function of the mutated genes and the specific therapy for certain sub-forms.

Wolfram syndrome: clinical and genetic profiling of a cohort from a tertiary care centre with characterization of the primary gonadal failure. Endocrine 2020; 69:420-429. [PMID: 32350710 DOI: 10.1007/s12020-020-02320-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/03/2020] [Accepted: 04/16/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND Wolfram syndrome (WFS) is a rare, monogenic neurodegenerative syndrome characterised by insulin requiring non-autoimmune diabetes mellitus (DM) and optic atrophy which are usually the earliest and commonest manifestations. However, there are other features which are under-recognized, adding to morbidity and premature mortality in these patients. METHODS Five patients (three males, two females) with genetically confirmed WFS at a single tertiary care centre were prospectively followed up. Their symptomatology, clinical profile, genetic analysis and radiology were analyzed. Multidisciplinary approach was used for comprehensive clinical care of this cohort. Patients with primary gonadal failure were subjected to biopsy and immunohistochemistry (IHC) for wolframin was performed. RESULTS DM was the earliest presenting manifestation at 6.2 ± 1.3 years followed by optic atrophy at 10.4 ± 2.3 years, diabetes insipidus at 12 ± 2.1 years and deafness at 12.8 ± 2.1 years. All patients were autoantibody negative with low C-peptide(<0.6 ng/ml). Hypoglycemic episodes were frequent (upto 60%) but there was no instance of diabetic ketoacidosis. Optic atrophy was present alongwith proliferative diabetic retinopathy and cataract in 40%. Uncommon manifestations included neuropsychiatric features, parasuicide, cystopathy, brainstem atrophy and hypergonadotropic hypogonadism only in adult males (n = 2). Testicular biopsy revealed partly hyalinised seminiferous tubules and prominence of Leydig cells. IHC confirmed the presence of mutated wolframin, which was not significantly different from normal testis specimen on protein quantification. CONCLUSIONS WFS requires a multidisciplinary approach with special emphasis on early diagnosis and management of other endocrine and non-endocrine features so as to improve long-term outcomes. Gonadal functions need periodic assessment, especially in adult males.
