| Distal myopathies v6.13 | HNRNPA1 | Ida Ertmanska commented on gene: HNRNPA1: Comment on list classification: There are at least 7 unrelated individuals reported in literature with monoallelic variants in HNRNPA1 that presented with distal myopathy. Disease onset is either juvenile or in early adulthood. The affected individuals harboured stop-loss, missense, and frameshift variants, either de novo or shown to segregated with disease in an autosomal dominant manner. Other variants in this gene have been reported as causal for juvenile-onset ALS, multisystem proteinopathy, and distal hereditary motor neuropathy. There is currently little to no correlation between the location of the causative variant and the corresponding phenotype, and no precise understanding of the different disease mechanisms. Nonetheless, there is sufficient evidence for this gene-disease relationship. HNRNPA1 should be promoted to Green for Distal myopathies at the next GMS update. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
