Genes affected

USP33 (HGNC:20059): (ubiquitin specific peptidase 33) This gene encodes a deubiquinating enzyme important in a variety of processes, including Slit-dependent cell migration and beta-2 adrenergic receptor signaling. The protein is negatively regulated through ubiquitination by von Hippel-Lindau tumor protein (VHL). Alternative splicing results in multiple transcript variants and protein isoforms.

The c.1603G>A (p.E535K) alteration is located in exon 14 (coding exon 13) of the USP33 gene. This alteration results from a G to A substitution at nucleotide position 1603, causing the glutamic acid (E) at amino acid position 535 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
