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]

Collection Method: clinical testing

The c.184G>A (p.E62K) alteration is located in exon 1 (coding exon 1) of the UBR3 gene. This alteration results from a G to A substitution at nucleotide position 184, causing the glutamic acid (E) at amino acid position 62 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
