Genes affected

SENP7 (HGNC:30402): (SUMO specific peptidase 7) The reversible posttranslational modification of proteins by the addition of small ubiquitin-like SUMO proteins (see SUMO1; MIM 601912) is required for many cellular processes. SUMO-specific proteases, such as SENP7, process SUMO precursors to generate a C-terminal diglycine motif required for the conjugation reaction. They also display isopeptidase activity for deconjugation of SUMO-conjugated substrates (Lima and Reverter, 2008 [PubMed 18799455]).[supplied by OMIM, Jun 2009]

SENP7 Gene-Disease associations (from GenCC):

• arthrogryposis multiplex congenita

  Inheritance: AR Classification: STRONG Submitted by: PanelApp Australia
