GOMEZ-LOPEZ, Mariana Teresa; BOTERO-MENESES, Juan Sebastián; TIERRADENTRO-GARCIA, Luis Octavio y VELEZ-VAN-MEERBEKE, Alberto. Type 1 neurofibromatosis: genotype-phenotype relationship. Acta Neurol Colomb. [online]. 2020, vol.36, n.2, pp.93-99. ISSN 0120-8748. https://doi.org/10.22379/24224022284.
INTRODUCTION:
Neurofibromatosis (von Recklinghausen disease) is an autosomal dominant disease that mainly presents cutaneous and neurological manifestations. The objective is to describe if there is a relationship between the mutations found in patients with neurofibromatosis type 1 and the clinical characteristics they present.
METHODS:
A narrative review of the literature was carried out in relation to the genotype and phenotype of patients with Neurofibromatosis type 1 using PubMed, Embase, and Lilacs. The following Mesh terms were used: Neurofibromatosis, neurofibromatosis type 1, genes, genotype, phenotype, mutations, exome sequencing. The identified studies were reviewed and analyzed. Data are presented qualitatively
RESULTS:
Of 425 articles, 62 contained the information necessary to make the analysis. Although some studies have presented evidence of association in relation to the mutations found and the clinical one, there is still no proven genotype-phenotype correlation in neurofibromatosis type 1. This suggests that, for discordant phenotypes with a similar genotype, there are other factors that must be considered such as epigenetics, genetic alterations or even environmental factors.
CONCLUSIONS:
It is necessary to perform studies with larger cohort of patients to continue studying whether there is a direct relationship or not.
