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 GeneticsDec 28, 2023The c.217G>A (p.V73I) alteration is located in exon 5 (coding exon 4) of the NAP1L1 gene. This alteration results from a G to A substitution at nucleotide position 217, causing the valine (V) at amino acid position 73 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
