Genes affected

UBOX5 (HGNC:17777): (U-box domain containing 5) This gene encodes a U-box domain containing protein. The encoded protein interacts with E2 enzymes and may play a role in the ubiquitination pathway. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Jun 2012]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.980G>A (p.R327Q) alteration is located in exon 3 (coding exon 2) of the UBOX5 gene. This alteration results from a G to A substitution at nucleotide position 980, causing the arginine (R) at amino acid position 327 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
