Genes affected
OTUB2 (HGNC:20351): (OTU deubiquitinase, ubiquitin aldehyde binding 2) This gene encodes one of several deubiquitylating enzymes. Ubiquitin modification of proteins is needed for their stability and function; to reverse the process, deubiquityling enzymes remove ubiquitin. This protein contains an OTU domain and binds Ubal (ubiquitin aldehyde); an active cysteine protease site is present in the OTU domain. [provided by RefSeq, Aug 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2024The c.97G>A (p.E33K) alteration is located in exon 2 (coding exon 2) of the OTUB2 gene. This alteration results from a G to A substitution at nucleotide position 97, causing the glutamic acid (E) at amino acid position 33 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
