Genes affected

NAP1L4 (HGNC:7640): (nucleosome assembly protein 1 like 4) This gene encodes a member of the nucleosome assembly protein (NAP) family which can interact with both core and linker histones. It can shuttle between the cytoplasm and nucleus, suggesting a role as a histone chaperone. This gene is one of several located near the imprinted gene domain of 11p15.5, an important tumor-suppressor gene region. Alterations in this region have been associated with the Beckwith-Wiedemann syndrome, Wilms tumor, rhabdomyosarcoma, adrenocortical carcinoma, and lung, ovarian, and breast cancer.

May 05, 2023

The c.604A>G (p.M202V) alteration is located in exon 8 (coding exon 7) of the NAP1L4 gene. This alteration results from a A to G substitution at nucleotide position 604, causing the methionine (M) at amino acid position 202 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
