Brown-Vialetto-Van Laere syndrome 1
A rare neurologic disorder characterized by sensorineural hearing loss and a variety of cranial nerve palsies, which develop over a relatively short period of time in a previously healthy individual. Sensorineural hearing loss may precede the neurological signs. The course is invariably progressive, but the rate of decline is variable within and between families. With disease evolution, long tract signs, lower motor neuron signs, cerebellar ataxia and lower cranial nerve (III-VI) palsies develop, giving rise to a complex picture resembling amyotrophic lateral sclerosis. Diaphragmatic weakness and respiratory compromise are some of the most distressing features, leading to recurrent chest infections and respiratory failure, which are often the cause of patients' demise.

Case Report: SLC52A2 variants cause Brown-Vialetto-Van Laere syndrome type 2, characterized by pure red cell aplastic anemia: clinical and genetic features of three Chinese children.
To report three Chinese pediatric cases of Brown-Vialetto-Van Laere syndrome type 2 (BVVLS2) presenting with pure red cell aplasia (PRCA) as the core manifestation, and to analyze their clinical features, molecular basis, and response to riboflavin therapy. We conducted a retrospective analysis of three pediatric cases, integrating detailed clinical phenotyping with comprehensive genetic analysis (including whole-exome/targeted sequencing, Sanger validation, and ACMG-based variant interpretation). To elucidate genotype-phenotype correlations, we interpreted these findings in the context of a literature review. All three patients carried compound heterozygous variants in the SLC52A2 gene. Each exhibited early-onset PRCA (onset age: 2 days to 6 months; hemoglobin: 29-67 g/L) and progressive neurodegeneration, including motor regression, axonal peripheral neuropathy, and sensorineural hearing loss. Riboflavin supplementation led to normalization of hemoglobin levels within four weeks and marked improvement in neurological function. This case series provides detailed longitudinal data on riboflavin-responsive PRCA as a core presenting feature of BVVLS2 and reports rare SLC52A2 variants in the Chinese population. Early riboflavin treatment effectively reversed anemia and partially improved neurological deficits, which may inform a new diagnostic and therapeutic approach for unexplained PRCA accompanied by neurodegenerative features.
msCNN-PLM-FAD: Enhanced predicting FAD binding sites by using protein language representation combined with multiple separable windows convolutional neural networks.
The FAD binding sites classification problem is crucial because it is directly related to many diseases, such as flavoprotein-associated diseases, developmental disorders, digestive and lipid metabolism abnormalities, anemia, cancer, cardiovascular diseases, and neurological diseases. Researchers have conducted numerous studies to classify FAD binding sites, achieving varying levels of effectiveness. Nevertheless, significant potential for enhancement persists. Our study proposes msCNN-PLM-FAD, an innovative computational model predicting FAD binding sites in electron transport proteins using a sliding window feature extraction technique and pretrained protein language models (PLMs). Our approach combines a convolutional neural network-based window scanning technique able to capture various sequence features relevant to FAD binding sites with embeddings from the ESM PLM. Built on a dataset of 12,850 samples, the model outperformed previous studies, particularly in class-balance metrics, with an area under the curve (AUC) of 0.9614 and a Matthews correlation coefficient (MCC) of 0.7491, specificity of 0.9836, and accuracy of 0.9795, while maintaining a sensitivity of 0.8704. The results of this study demonstrate the potential to improve the accuracy of FAD binding site prediction, thereby promoting the development of drugs for diseases associated with FAD deficiency as well as therapeutic approaches that target bacterial FAD synthesis without affecting human health.
Altered dimerization of certain riboflavin transporter 2 mutants: a possible source of UPR, altered calcium signalling and mitochondrial derangements in RTD2.
Riboflavin transporter deficiency Type 2 (RTD2, OMIM #614707), formerly known as Brown-Vialetto-Van Laere Syndrome 2 (BVVLS 2), is a rare autosomal recessive neurodegenerative disorder caused by biallelic variants in the SLC52A2 gene, encoding for riboflavin transporter 2 (RFVT2). This transporter plays a critical role in flavin cofactor delivery, particularly in the brain. Clinically, RTD2 presents with progressive hearing loss, optic atrophy, muscle weakness, respiratory issues, and pontobulbar palsy. Current treatment involves high-dose riboflavin and other supplements. In this study we explored the molecular mechanisms behind RTD2, focusing on the dimerization of RFVT2 and the associated cellular stress mechanisms in patient-specific models. We demonstrated that RFVT2 exists as a homodimer and that pathogenic variants significantly impair its dimerization, which may contribute to the induction of ER stress. This hypothesis was supported by elevated levels of BiP, an ER stress marker, in patient iPSC-derived motor neurons. Similar findings were confirmed in patient-derived fibroblasts, where we also observed mitochondrial dysfunction and disrupted calcium signaling. Interestingly, no significant changes in FAD content were detected in both cell models, suggesting that proteotoxic stress may be a crucial pathogenic mechanism in RTD2, even in the absence of signs of FAD deficiency. FAD autofluorescence and FLIM measurements reinforce the occurrence of mitochondrial dysfunction in patient MNs. These findings provide insight into the pathogenic mechanisms of RTD2, highlighting the critical role of RFVT2 misfolding, ER stress, and mitochondrial dysfunction in this neurodegenerative disorder.
Atypical phenotypic characteristics, mutation analysis and treatment in a family of riboflavin transporter deficiency caused by SLC52A3 variants.
Variants in the SLC52A3 gene have been associated with riboflavin transporter deficiency type 3 (RTD3), a severe neurodegenerative disorder, typically inherited in an autosomal recessive manner. In this study, two SLC52A3 variants (NM_033409.4: c.62A > G [p.Asn21Ser] and c.161G > A [p.Gly54Glu]) were identified in a family with hereditary hearing loss through whole-exome sequencing. The compound heterozygous proband exhibited only late-onset, progressive, and symmetric sensorineural hearing loss over 23 yr, along with unilateral facial muscle spasm. A heterozygous carrier of the c.62A > G variant also exhibited optic nerve dysfunction, while no other neurological abnormalities were observed in the family. Although the proband's decreased serum riboflavin level has been improved through supplementation, no significant clinical improvement was observed. These findings further support the phenotypic variability, incomplete penetrance, and a potential autosomal dominant inheritance pattern of RTD3. We also underscore the importance of early genetic testing, timely and sustained riboflavin supplementation, and long-term follow-up in affected individuals.
Identification of Riboflavin Metabolism Pathway in HepG2 Cells Expressing Genotype IV Swine Hepatitis E Virus ORF3 Protein.
(1) Background: Hepatitis E (HE) is a novel zoonotic disease caused by hepatitis E virus (HEV). In particular, swine hepatitis E virus (SHEV) genotype IV is one of the main genotypes that infect humans. Open reading frame 3 (ORF3) is an important virulence protein of SHEV, which is involved in virus assembly, release, and regulation of host cell signaling pathways. Circular RNAs (circRNAs), as a type of competitive endogenous RNA (ceRNA), have a closed-loop structure and are special non-coding RNA molecules. They participates in the regulation of multiple biological processes by adsorbing microRNAs (miRNAs). Riboflavin, also known as vitamin B2, is a component of the coenzyme of flavoenzymes in the body. When there is a deficiency of riboflavin, it will affect the biological oxidation process of the host, leading to metabolic disorders. In addition, riboflavin can also affect the synthesis, transportation and decomposition of lipids in the body. It mainly maintains the normal transportation process of fat in the liver. Therefore, the deficiency of riboflavin will lead to the disorder of lipid metabolism in the body. Thus, viral hepatitis is closely related to riboflavin metabolism. However, there are very few reports on SHEV ORF3 affecting the riboflavin metabolism of target cells and thereby influencing viral infection. Therefore, this study investigates this highly significant scientific issue. (2) Methods: In the previous research of our group, adenovirus was used to mediate the overexpression of SHEV ORF3 genotype IV in HepG2 cells. Total RNA was extracted for high-throughput sequencing of circRNAs and transcriptome. KEGG functional enrichment analysis was performed on the data to identify the differentially expressed circRNAs and miRNAs after SHEV infection, and the relevant circRNA-miRNA network in the riboflavin metabolism pathway in HepG2 cells was found. (3) Results: We identified 4 circRNAs in the riboflavin metabolism pathway of HepG2 cells expressing the ORF3 protein of SHEV genotype IV and successfully found 26 relevant circRNA-miRNA networks. (4) Conclusion: We successfully screened and identified circRNAs related to riboflavin metabolism, further identifying the circRNA-miRNA network and its functional targets. For the first time, we investigated the key mechanism by which ORF3 protein influences riboflavin metabolic pathways in target cells through circRNAs, preliminarily revealing that ariboflavinosis can lead to lipid metabolic disorder in the organism. This indicates a close association between viral HE and riboflavin metabolism.
