Descripción general
-
Los síndromes de Ehlers-Danlos (EDS) son un grupo heterogéneo clínica y genéticamente de trastornos del tejido conectivo, donde el defecto genético afecta la síntesis y estructura del colágeno y del tejido conectivo. Se caracteriza por hipermovilidad, fragilidad cutánea e hiperextensibilidad. Dado que el tejido conectivo es el tejido que ayuda al crecimiento del cuerpo y sirve como andamio para las células y los órganos, Ehlers-Danlos es un síndrome pleiotrópico que afecta la piel, las articulaciones y los vasos sanguíneos. Clásicamente se ha dividido en seis tipos (clásico, hipermóvil, vascular, cifoescoliótico, artrocalasis y dermatosparaxis), donde la anomalía del colágeno subyacente es diferente para cada tipo. En algunos casos, la EDS puede poner en peligro la vida, mientras que en otros, las personas llevan una vida relativamente tranquila. El SED puede tener una superposición fenotípica con afecciones como la enfermedad de Marfan y la cutis laxa.
-
El panel de precisión del síndrome de Igenomix Ehlers-Danlos se puede utilizar para realizar un diagnóstico preciso y directo, así como un diagnóstico diferencial de los trastornos del tejido conectivo debido a sus características fenotípicas superpuestas, lo que finalmente conduce a un mejor manejo y pronóstico de la enfermedad. Proporciona un análisis completo de los genes involucrados en esta enfermedad utilizando secuenciación de próxima generación (NGS) para comprender completamente el espectro de genes relevantes involucrados.
Indicaciones
El panel de precisión del síndrome de Igenomix Ehlers-Danlos está indicado para aquellos pacientes con sospecha clínica o diagnóstico de SED que presenten:
-
Hiperextensibilidad de la piel
-
Hipermovilidad articular
-
Moretones con facilidad
-
Desprendimiento de retina
-
Prolapso de la válvula mitral
-
Hernias y prolapso de órganos
-
Anomalías esqueléticas: pectus excavatum, paladar arqueado alto, pie plano
-
Problemas digestivos: acidez y estreñimiento
-
Incontinencia urinaria de esfuerzo
Utilidad clínica
La utilidad clínica de este panel es:
-
La confirmación genética y molecular para un diagnóstico clínico preciso de un paciente sintomático. Existe una superposición clínica entre los diferentes subtipos de SED, así como con otros trastornos hereditarios del tejido conectivo, por lo que el diagnóstico se basa en la confirmación molecular con la identificación genética de los genes causantes.
-
Inicio precoz del tratamiento con un equipo multidisciplinar en forma de fisioterapia y vigilancia para prevenir complicaciones vasculares.
- Evaluación de riesgos y asesoramiento genético de familiares asintomáticos según modalidad hereditaria.
- Mejora de la delimitación de la correlación genotipo-fenotipo.
