Genes affected
NAA25 (HGNC:25783): (N-alpha-acetyltransferase 25, NatB auxiliary subunit) This gene encodes the auxiliary subunit of the heteromeric N-terminal acetyltransferase B complex. This complex acetylates methionine residues that are followed by acidic or asparagine residues.[provided by RefSeq, Mar 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 05, 2023The c.1917C>G (p.N639K) alteration is located in exon 17 (coding exon 17) of the NAA25 gene. This alteration results from a C to G substitution at nucleotide position 1917, causing the asparagine (N) at amino acid position 639 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
