T2*-weighted scan of COL4A1-related disorder |
Despite recent progress
in molecular screening and diagnostic imaging, adult-onset genetic
leukoencephalopathies are still a common cause of misdiagnosis with potentially
severe consequences. Missing a genetic cause may lead to a false diagnosis of
an acquired disorder with putative prescription of inaccurate treatments (eg,
corticosteroids, immunosuppression) and to the absence of any offer of genetic
counseling, therefore leading the patient and his or her family to not
receiving the best possible chances for diagnosis and treatment .
Excellent review, with diagnostic algorithm
In February 2018, our group will hold the first symposium on diagnosis and counseling in the diagnosis of leukodystrophy in adult presentation.
We hope to have excellent speaker of the state of the art in this subject.

A pesar de los recientes avances en la detección
molecular y de imágenes diagnósticas, la leucoencefalopatía genética de inicio en
los adultos sigue siendo una causa común de diagnósticos erróneos con
consecuencias potencialmente graves. La ausencia de una causa genética puede
conducir a un error diagnóstico de un trastorno adquirido con presunta
prescripción de tratamientos inexactos (por ejemplo, corticosteroides,
inmunosupresión) y la ausencia de cualquier oferta de asesoramiento genético,
lo que lleva al paciente ya la familia a no recibir mejores posibilidades de
diagnóstico y el tratamiento.
Excelente revisión, con algoritmo de
diagnóstico.
En febrero de 2018, nuestro grupo realizara el primer simposio sobre diagnóstico y orientación en el diagnóstico de leucodistrofia en presentación de adultos.
Esperamos tener excelentes expositores del estado del arte en este tema.
