Genes affected

NPLOC4 (HGNC:18261): (NPL4 homolog, ubiquitin recognition factor) Predicted to enable ATPase binding activity; ubiquitin binding activity; and ubiquitin protein ligase binding activity. Predicted to contribute to K48-linked polyubiquitin modification-dependent protein binding activity and K63-linked polyubiquitin modification-dependent protein binding activity. Involved in negative regulation of RIG-I signaling pathway; negative regulation of type I interferon production; and proteolysis involved in cellular protein catabolic process. Located in nucleus. Part of UFD1-NPL4 complex and VCP-NPL4-UFD1 AAA ATPase complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.198G>C (p.L66F) alteration is located in exon 3 (coding exon 3) of the NPLOC4 gene. This alteration results from a G to C substitution at nucleotide position 198, causing the leucine (L) at amino acid position 66 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
