Genes affected

UCHL5 (HGNC:19678): (ubiquitin C-terminal hydrolase L5) Enables endopeptidase inhibitor activity; proteasome binding activity; and thiol-dependent deubiquitinase. Involved in negative regulation of proteasomal ubiquitin-dependent protein catabolic process; positive regulation of smoothened signaling pathway; and protein deubiquitination. Located in cytosol; nucleolus; and nucleoplasm. Colocalizes with Ino80 complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

The c.442A>G (p.M148V) alteration is located in exon 6 (coding exon 6) of the UCHL5 gene. This alteration results from a A to G substitution at nucleotide position 442, causing the methionine (M) at amino acid position 148 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
