dc.description.abstract | Introduction and objective: Noonan syndrome (NS) is a genetic disorder characterized by a wide range ofdistinctive features and health problems. It caused in 50% of cases by missense mutations in PTPN11 gene.It has been postulated that it is possible to predict the disease course based into the impact of mutationson the protein.Patients and methods: We report two cases of severe NS phenotype including hydrops fetalis. PTPN11gene was studied in germinal cells of both patients by sequencing.Results: Two different mutations (p.Gly503Arg and p.Met504Val) was detected in PTPN11 gene.Discussion: These mutations have been reported previously, and when they were germinal variants,patients presented classic NS, NS with other malignancies and recently, p.Gly503Arg has been alsoobserved in a patient with severe NS and hydrops fetalis, as our cases. Therefore, these observationsshade light on that it is not always possibly to determine the genotype-phenotype relation based intothe impact of mutations on the protein in NS patients with PTPN11 mutations. | |
dc.description.abstract | Introducción y objetivo: El síndrome de Noonan (SN) es un trastorno genético caracterizado por una ampliagama de signos distintivos y problemas de salud. Está causado en el 50% de los casos por mutacionesmissense en el gen PTPN11. Se ha postulado que es posible predecir el curso de la enfermedad en funcióndel impacto de las mutaciones en la proteína.Pacientes y métodos: Presentamos 2 casos de fenotipo severo de SN con hydrops fetalis. En ambos casosse realizó la secuenciación del gen PTPN11 en células germinales.Resultados: Se identificaron 2 mutaciones diferentes en dicho gen (p.Gly503Arg y p.Met504Val).Discusión: Estas mutaciones ya han sido identificadas previamente, y cuando se presentan en líneagerminal, los pacientes pueden presentar SN clásico, SN con alteraciones malignas o recientemente,p.Gly503Arg se ha observado en un paciente con SN e hydrops fetalis, como los 2 casos que presenta-mos. Por tanto, estas observaciones muestran, que en pacientes con SN y mutaciones en el gen PTPN11,no es siempre posible determinar la relación genotipo-fenotipo en función del impacto de la mutaciónen la proteína. | |
