Ane Velasco led this work where we developed an in-house targeted 3´end RNA-sequencing approach to measure Huntingtin cryptic polyadenylation in HD. This study supports a model where long-somatic DNA repeat expansions acquired through aging drive neurodegeneration

Irene Santos-Garcia led this work where we employed MSD-Elisa technology to measure HDGFL2 cryptic peptide and Light Chain Neurofilament to monitor TDP-43 proteinopathies such as ALS and FTD due to mutations in GRN gene

This work describes novel molecular and clinical findings of SNUPN muscle dystrophy and confirms alterations in RNA-metabolism as a hallmark of the disease. It expands the phenotype of SNUPN-related muscular dystrophy and provides more insights into their pathological profile. We advise SNUPN testing in patients with late-onset proximo-distal and axial weakness with early respira- tory impairment and features reminding inclusion body myositis (IBM).
