Genes affected

RTN2 (HGNC:10468): (reticulon 2) This gene belongs to the family of reticulon encoding genes. Reticulons are associated with the endoplasmic reticulum, and are involved in neuroendocrine secretion or in membrane trafficking in neuroendocrine cells. Reticulon proteins also play an important role in the replication of positive-strand RNA (ssRNA) viruses. Mutations at this locus have been associated with autosomal dominant spastic paraplegia-12.

RTN2 links:

PPM1N (HGNC:26845): (protein phosphatase, Mg2+/Mn2+ dependent 1N (putative)) Predicted to enable metal ion binding activity and protein serine/threonine phosphatase activity. Predicted to be involved in negative regulation of I-kappaB kinase/NF-kappaB signaling and positive regulation of canonical Wnt signaling pathway. Predicted to be active in cytosol and nucleus.
