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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 23, 2023The c.453G>T (p.K151N) alteration is located in exon 7 (coding exon 6) of the NAP1L1 gene. This alteration results from a G to T substitution at nucleotide position 453, causing the lysine (K) at amino acid position 151 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
