Human genes for porphyria

Porphyria [DOID:13268]

The porphyrias are a group of inherited or acquired disorders of certain enzymes in the heme bio-synthetic pathway (also called porphyrin pathway). They manifest with either neurological complications ("acute") or skin problems ("cutaneous"), or occasionally both. The porphyrias may be classified by the primary site of the overproduction and accumulation of the porphyrins (or their chemical precursors) as hepatic porphyrias, where porphyrins are overproduced in the liver predominantly, or erythropoietic porphyrias, where the overproduction is confined to the bone marrow and the erythrocye (red blood cell) and its precursors.

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.
