El polimorfismo K153R del gen de la miostatina como gen candidato en la longevidad extrema de centenarias españolas

Abstract

El gen de la miostatina (MSTN) es uno de los genes candidatos que podría influir en la longevidad extrema, debido a su papel en la modulación de masa muscular y sarcopenia, además de su papel en la inhibición de la principal vía de señalización de nutrientes relacionada con la longevidad, mTOR (del inglés, ‘mammalian target-of-rapamycin’). Comparamos la distribución alélica/genotípica de las variantes exónicas de la MSTN K153R (rs1805086), E164K (rs35781413), I225T y P198A, en centenarias (casos, n=132; rango edad: 100-107) y mujeres jóvenes (controles, n=167, < 50 años). La frecuencia de la variante alélica R y de los portadores de este la misma (genotipos KR o RR) fue significativamente superior en centenarias (6.8% y 12.1%) que en controles (1.5% y 3.8%) (p=0.0008 y p=0.0022 respectivamente). La razón de verosimilitud (‘odds ratio’, abreviado ‘OR’) de ser un centenaria si el sujeto tiene un alelo-R fue 4.47 (con un intervalo de confianza del 95% (CI): 1.59-12.54; p=0.004), comparado con el grupo control. Aunque son necesarias nuevas investigaciones, el alelo variante R del polimorfismo MSTN K153R podría ser uno de los contribuidores genéticos asociados con excepcional longevidad.
