Genes affected

UBR3 (HGNC:30467): (ubiquitin protein ligase E3 component n-recognin 3) Predicted to enable ubiquitin protein ligase activity. Predicted to be involved in several processes, including cellular protein metabolic process; sensory perception of smell; and suckling behavior. Predicted to act upstream of or within in utero embryonic development and olfactory behavior. Predicted to be integral component of membrane. Predicted to be part of ubiquitin ligase complex. Predicted to be active in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

The UBR3 c.407G>A variant is predicted to result in the amino acid substitution p.Cys136Tyr. To our knowledge, this variant has not been reported in the literature or in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
