Genes affected

SPSB3 (HGNC:30629): (splA/ryanodine receptor domain and SOCS box containing 3) Predicted to be involved in proteasome-mediated ubiquitin-dependent protein catabolic process. Predicted to be located in cytosol. Predicted to be part of SCF ubiquitin ligase complex. [provided by Alliance of Genome Resources, Apr 2022]

SPSB3 links:

EME2 (HGNC:27289): (essential meiotic structure-specific endonuclease subunit 2) EME2 forms a heterodimer with MUS81 (MIM 606591) that functions as an XPF (MIM 278760)-type flap/fork endonuclease in DNA repair (Ciccia et al., 2007 [PubMed 17289582]).[supplied by OMIM, Mar 2008]

The c.616G>C (p.D206H) alteration is located in exon 6 (coding exon 5) of the SPSB3 gene. This alteration results from a G to C substitution at nucleotide position 616, causing the aspartic acid (D) at amino acid position 206 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
