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.2536A>G (p.T846A) alteration is located in exon 23 (coding exon 22) of the USP33 gene. This alteration results from a A to G substitution at nucleotide position 2536, causing the threonine (T) at amino acid position 846 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
