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]

Collection Method:clinical testing

The c.1715T>C (p.V572A) alteration is located in exon 17 (coding exon 17) of the NPLOC4 gene. This alteration results from a T to C substitution at nucleotide position 1715, causing the valine (V) at amino acid position 572 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
