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]

The c.2588G>A (p.R863Q) alteration is located in exon 22 (coding exon 22) of the NAA25 gene. This alteration results from a G to A substitution at nucleotide position 2588, causing the arginine (R) at amino acid position 863 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
