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.634G>A (p.A212T) alteration is located in exon 7 (coding exon 7) of the NPLOC4 gene. This alteration results from a G to A substitution at nucleotide position 634, causing the alanine (A) at amino acid position 212 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
