Human genes for purpura

Purpura [DOID:3326]

Purpura (from Latin: purpura, meaning "purple") is the appearance of red or purple discolorations on the skin that do not blanch on applying pressure. They are caused by bleeding underneath the skin. Purpura measure 0.3–1 cm (3–10 mm), whereas petechiae measure less than 3 mm, and ecchymoses greater than 1 cm.

The disease associations are derived via automatic text mining of the biomedical literature and have not been manually verified. The confidence of each association is signified by stars, where ★★★★☆ is the highest confidence and ★☆☆☆☆ is the lowest.

Each disease–gene association is based on a text-mining score, which is proportional to 1) the absolute number of comentionings and 2) the ratio of observed to expected comentionings (i.e. the enrichment). These scores are normalized to z-scores by comparing them to a random background. This is represented by stars, each star corresponding to two standard deviations above the mean of the background distribution.
