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]

Collection Method: clinical testing

The c.1478A>G (p.Y493C) alteration is located in exon 5 (coding exon 4) of the UBOX5 gene. This alteration results from a A to G substitution at nucleotide position 1478, causing the tyrosine (Y) at amino acid position 493 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
