Genes affected

SAE1 (HGNC:30660): (SUMO1 activating enzyme subunit 1) Posttranslational modification of proteins by the addition of the small protein SUMO (see SUMO1; MIM 601912), or sumoylation, regulates protein structure and intracellular localization. SAE1 and UBA2 (MIM 613295) form a heterodimer that functions as a SUMO-activating enzyme for the sumoylation of proteins (Okuma et al., 1999 [PubMed 9920803]).[supplied by OMIM, Mar 2010]

Collection Method: clinical testing

The c.703C>T (p.R235C) alteration is located in exon 6 (coding exon 6) of the SAE1 gene. This alteration results from a C to T substitution at nucleotide position 703, causing the arginine (R) at amino acid position 235 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
