Genes affected

NAP1L5 (HGNC:19968): (nucleosome assembly protein 1 like 5) This gene encodes a protein that shares sequence similarity to nucleosome assembly factors, but may be localized to the cytoplasm rather than the nucleus. Expression of this gene is downregulated in hepatocellular carcinomas. This gene is located within a differentially methylated region (DMR) and is imprinted and paternally expressed. There is a related pseudogene on chromosome 4. [provided by RefSeq, Nov 2015]

NAP1L5 links:

HERC3 (HGNC:4876): (HECT and RLD domain containing E3 ubiquitin protein ligase 3) This gene encodes a member the HERC ubiquitin ligase family. The encoded protein is located in the cytosol and binds ubiquitin via a HECT domain. Mutations in this gene have been associated with colorectal and gastric carcinomas. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Oct 2012]

Ambry Genetics

Dec 28, 2022

The c.10T>A (p.S4T) alteration is located in exon 1 (coding exon 1) of the NAP1L5 gene. This alteration results from a T to A substitution at nucleotide position 10, causing the serine (S) at amino acid position 4 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
