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 GeneticsNov 14, 2024The c.1846C>T (p.R616W) alteration is located in exon 16 (coding exon 16) of the NAA25 gene. This alteration results from a C to T substitution at nucleotide position 1846, causing the arginine (R) at amino acid position 616 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
