Online databases for mtDNA and Y chromosome polymorphisms in human populations.

This study presents an overview of online databases for mtDNA and Y chromosome polymorphisms in human populations. In order to provide readers with information which may help optimize their use, we focus on: (i) type, quantity and source of data contained; (ii) possibilities of downloading and uploading; (iii) availability of data filters and population genetics tools. We show that some of these databases offer a useful complement to the primary databases by giving access to additional data and making it possible to perform queries which exploit some specific metadata.

Mine, yours, ours? Sharing data on human genetic variation.

The achievement of a robust, effective and responsible form of data sharing is currently regarded as a priority for biological and bio-medical research. Empirical evaluations of data sharing may be regarded as an indispensable first step in the identification of critical aspects and the development of strategies aimed at increasing availability of research data for the scientific community as a whole. Research concerning human genetic variation represents a potential forerunner in the establishment of widespread sharing of primary datasets.
