Genes affected

SENP2 (HGNC:23116): (SUMO specific peptidase 2) SUMO1 (UBL1; MIM 601912) is a small ubiquitin-like protein that can be covalently conjugated to other proteins. SENP2 is one of a group of enzymes that process newly synthesized SUMO1 into the conjugatable form and catalyze the deconjugation of SUMO1-containing species.[supplied by OMIM, Apr 2004]

The c.497G>A (p.R166H) alteration is located in exon 6 (coding exon 6) of the SENP2 gene. This alteration results from a G to A substitution at nucleotide position 497, causing the arginine (R) at amino acid position 166 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
