Genes affected

UCHL3 (HGNC:12515): (ubiquitin C-terminal hydrolase L3) The protein encoded by this gene is a member of the deubiquitinating enzyme family. Members of this family are proteases that catalyze the removal of ubiquitin from polypeptides and are divided into five classes, depending on the mechanism of catalysis. This protein may hydrolyze the ubiquitinyl-N-epsilon amide bond of ubiquitinated proteins to regenerate ubiquitin for another catalytic cycle. Alternative splicing results in multiple transcript variants that encode different protein isoforms. [provided by RefSeq, Aug 2012]

Collection Method: clinical testing

The c.167T>A (p.F56Y) alteration is located in exon 3 (coding exon 3) of the UCHL3 gene. This alteration results from a T to A substitution at nucleotide position 167, causing the phenylalanine (F) at amino acid position 56 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
