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 15, 2024The c.2383A>T (p.M795L) alteration is located in exon 20 (coding exon 20) of the NAA25 gene. This alteration results from a A to T substitution at nucleotide position 2383, causing the methionine (M) at amino acid position 795 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
