Genes affected

ZUP1 (HGNC:21224): (zinc finger containing ubiquitin peptidase 1) This gene encodes a protein containing zinc finger motifs and a cysteine peptidase domain. The encoded protein functions as a K63-specific de-ubiquitinating enzyme that specifically cleaves long K63-linked polyubiquitin chains in the middle of a chain (i.e. "endo cleavage) rather than by removing the terminal ubiquitin from a chain. This enzyme is thought to be involved in the regulation of DNA repair by cleaving K63-linked ubiquitin chains at repair foci. This protein is related to proteases for the ubiquitin-like modifiers Ufm1 (ubiquitin fold modifier 1) and Atg8/Gabarapl2, but does not have any activity on these modifiers.

The c.476G>A (p.C159Y) alteration is located in exon 2 (coding exon 1) of the ZUFSP gene. This alteration results from a G to A substitution at nucleotide position 476, causing the cysteine (C) at amino acid position 159 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
