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]

Pathogenic:3

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Mar 11, 2019	Loss-of-function variants in NAA15 are known to be pathogenic (PMID: 28191889, 29656860). For these reasons, this variant has been classified as Pathogenic. This variant has been observed in an individual affected with autism spectrum disorder (PMID:¬†28191889). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Asp76Glufs*20) in the NAA15 gene. It is expected to result in an absent or disrupted protein product. -
