Mutations in the MATR3 gene have been linked to ALS, with this case being the first to report duplication in exons 15 and 16. The patient presented with limb-onset ALS and a complex medical history, including autoimmune conditions, suggesting a potential role of MATR3 mutations in this peculiar ALS phenotype.
Mutations in Matrin-3 (MATR3) gene have been described in ALS, suggesting a role for this gene in the disease pathogenesis. While most of MATR3 mutations are point mutations, here we report the first case of ALS associated with duplication in exons 15 and 16. The patient presented with limb-onset ALS and a complex past medical history because of Sjogren syndrome, antiphospholipid antibodies positivity, polyallergies, endometriosis, aldosterone-secreting adrenal cortical adenoma, congenital vesicoureteral reflux, and right breast hypoplasia. We discuss MATR3 effect in ALS and the role of this previously undescribed mutation in this peculiar ALS phenotype associated with systemic autoimmunity involvement.
