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]

The c.2819C>T (p.S940F) alteration is located in exon 22 (coding exon 22) of the SENP7 gene. This alteration results from a C to T substitution at nucleotide position 2819, causing the serine (S) at amino acid position 940 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
