Brown–Vialetto–Van Laere syndrome (BVVLS) is a rare autosomal recessive neurodegenerative disorder caused by pathogenic variants in riboflavin transporter genes. We report an 11-year boy who presented with progressive myopathy. In view of the progressive neuromuscular phenotype, whole-exome sequencing was performed,which identified a homozygous missense variant in the SLC52A2 gene, c.401C>T (p.Pro134Leu), associated with Brown–Vialetto–Van Laere syndrome type 2. Although classified as a likely pathogenic, the patient’s clinical features demonstrated a strong phenotypic correlation with SLC52A2-related riboflavin transporter deficiency. This case expands the clinical and genetic spectrum of SLC52A2-associated disease and highlights the importance of genetic testing in children with unexplained progressive neuromuscular weakness.
