Genes affected

USP43 (HGNC:20072): (ubiquitin specific peptidase 43) Predicted to enable ISG15-specific protease activity. Predicted to be involved in translesion synthesis. Predicted to be located in nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

USP43 links:

CFAP52 (HGNC:16053): (cilia and flagella associated protein 52) WD repeat-containing proteins, such as WDR16, play crucial roles in a wide range of physiologic functions, including signal transduction, RNA processing, remodeling the cytoskeleton, regulation of vesicular traffic, and cell division (Silva et al., 2005 [PubMed 15967112]).[supplied by OMIM, Mar 2008]

Collection Method: clinical testing

The c.58C>G (p.R20G) alteration is located in exon 1 (coding exon 1) of the USP43 gene. This alteration results from a C to G substitution at nucleotide position 58, causing the arginine (R) at amino acid position 20 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
