RESUMEN
A promising alternative to comprehensively performing genomics experiments is to, instead, perform a subset of experiments and use computational methods to impute the remainder. However, identifying the best imputation methods and what measures meaningfully evaluate performance are open questions. We address these questions by comprehensively analyzing 23 methods from the ENCODE Imputation Challenge. We find that imputation evaluations are challenging and confounded by distributional shifts from differences in data collection and processing over time, the amount of available data, and redundancy among performance measures. Our analyses suggest simple steps for overcoming these issues and promising directions for more robust research.

Tick borne encephalitis virus infection usually shows a biphasic course. In the first stage of illness symptoms are similar to a flu-like syndrome, then after a defervescence period, fever may represent with neurological manifestations ranging from mild meningitis to severe encephalomyelitis. We report the clinical case of an adult man presented with an acute proximal hyposthenia, severe hyperckemia, clinical and laboratoristic evidence of acute tick borne virus infection. This virus has a favourite tropism for the anterior horn cells of the cervical spine segment. Polio-like syndrome, usually affecting the upper limbs, is the clinical phenotype of an infection of the cervical motoneurons. Usually myelitis is associated to severe encephalitis and a complete diagnosis may be difficult in comatose patients. Rarely, an isolated polio-like syndrome may be the sole neurological complication of tick-borne encephalitis.
