Genes affected

NAA15 (HGNC:30782): (N-alpha-acetyltransferase 15, NatA auxiliary subunit) N-alpha-acetylation is among the most common post-translational protein modifications in eukaryotic cells. This process involves the transfer of an acetyl group from acetyl-coenzyme A to the alpha-amino group on a nascent polypeptide and is essential for normal cell function. This gene encodes the auxillary subunit of the N-terminal acetyltransferase A (NatA) complex. [provided by RefSeq, Jan 2017]

The NAA15 c.239_240delAT variant is predicted to result in a frameshift and premature protein termination (p.His80Argfs*17). This variant was reported to be a recurrent causative variant in patients with autism and intellectual disability; in at least two individuals, this variant was found to be de novo (Cheng et al. 2018. PubMed ID: 29656860; Stessman et al. 2017. PubMed ID: 28191889, Table S19). This variant is reported in 0.0036% of alleles in individuals of South Asian descent in gnomAD. Frameshift variants in NAA15 are expected to be pathogenic. This variant is interpreted as pathogenic. -
