Genotype-Phenotype correlations in Neuromuscular Disorders
The most recent scientific advancements have been able to provide a conclusive genetic diagnosis to an increasing number of patients. However, the observed clinical picture often diverges from the expected one and the disease course is to some extent difficult to predict. This group aims to identify those underlying mechanisms explaining the divergences often observed in neuromuscular diseases, a class of diseases affecting muscular function. The work will directly benefit patients, facilitating a proper diagnosis and prognosis and paving the way to possible therapies.
The rapid technological progress in genomics has reshaped the field of medical genetics, increasing the diagnostic rate and enabling the identification of a large number of novel disease genes responsible for Mendelian diseases. The classic paradigm ´one gene-one disease' has been definitively overcome. Causative variants in the same gene often result in a wide spectrum of phenotypes and a specific clinical phenotype can be caused by variants in several genes. The complex genetic architecture underlying human diseases has not been fully clarified and we still lack a clear-cut genotype–phenotype correlation for most genetic disorders.
Neuromuscular diseases are a useful study model to identify the molecular mechanisms underlying the often-observed discordance between the identified genotype and the expected phenotype.
This group have contributed to better characterize several genetic skeletal diseases, including titin-related myopathies, actininopathies and anoctaminopathies. Through a combination of state-of-art methods and a large network of international collaborators, the aim is to dissect the molecular mechanisms underlying the heterogenous phenotypes we observe in patients with neuromuscular diseases, facilitating the diagnostic and prognostic process and, thereby, the development of disease therapies.
