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]
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 06, 2023The c.1031C>T (p.P344L) alteration is located in exon 7 (coding exon 6) of the SPSB3 gene. This alteration results from a C to T substitution at nucleotide position 1031, causing the proline (P) at amino acid position 344 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
