Genes affected

NAP1L1 (HGNC:7637): (nucleosome assembly protein 1 like 1) This gene encodes a member of the nucleosome assembly protein (NAP) family. This protein participates in DNA replication and may play a role in modulating chromatin formation and contribute to the regulation of cell proliferation. Alternative splicing results in multiple transcript variants encoding different isoforms; however, not all have been fully described. [provided by RefSeq, Apr 2015]

Ambry Genetics

Jun 29, 2022

The c.25C>G (p.Q9E) alteration is located in exon 3 (coding exon 2) of the NAP1L1 gene. This alteration results from a C to G substitution at nucleotide position 25, causing the glutamine (Q) at amino acid position 9 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
