Targeted gene under study



We recently described a new form of distal hereditary motor neuropathy caused by bi-allelic variants in the VWA1 gene in 10 families (PMID: 33559681). We would like to include more new patients to delineate the phenotypic and genetic spectrum of the disorder. Our initial findings suggested that the clinical presentation ranges from motor neuropathies to myopathies. We would like to receive detailed clinical and genetic data of patients with bi-allelic VWA1 variants.
