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]

The c.124G>A (p.G42R) alteration is located in exon 1 (coding exon 1) of the USP43 gene. This alteration results from a G to A substitution at nucleotide position 124, causing the glycine (G) at amino acid position 42 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
