"Scientific Data" is a new journal from Nature Publishing Group that publishes genetic data that are valuable for the scientific community. Since the data is peer-reviewed, your data published there will get a larger scientific credit and will reach a broader community. Besides, it will be easier to reuse previously published data.
From the website of the journal (http://www.nature.com/sdata/): "Scientific Data is an open-access, peer-reviewed publication for descriptions of scientifically valuable datasets. Our primary article-type, the Data Descriptor, is designed to make your data more discoverable, interpretable and reusable."
