Abstract
The NatA N-acetyltransferase complex is important for cotranslational protein modification and regulation of multiple cellular processes. The NatA complex includes the core components of NAA10, the catalytic subunit, and NAA15, the auxiliary component. Both NAA10 and NAA15 have been associated with neurodevelopmental disorders with overlapping clinical features, including variable intellectual disability, dysmorphic facial features, and, less commonly, congenital anomalies such as cleft lip or palate. Cardiac arrhythmias, including long QT syndrome, ventricular tachycardia, and ventricular fibrillation were among the first reported cardiac manifestations in patients with NAA10-related syndrome. Recently, three individuals with NAA10-related syndrome have been reported to also have hypertrophic cardiomyopathy (HCM). The general and cardiac phenotypes of NAA15-related syndrome are not as well described as NAA10-related syndrome. Congenital heart disease, including ventricular septal defects, and arrhythmias, such as ectopic atrial tachycardia, have been reported in a small proportion of patients with NAA15-related syndrome. Given the relationship between NAA10 and NAA15, we propose that HCM is also likely to occur in NAA15-related disorder. We present two patients with pediatric HCM found to have NAA15-related disorder via exome sequencing, providing the first evidence that variants in NAA15 can cause HCM.

Abstract
N-alpha-acetylation is a common co-translational protein modification that is essential for normal cell function in humans. We previously identified the genetic basis of an X-linked infantile lethal Mendelian disorder involving a c.109T>C (p.Ser37Pro) missense variant in NAA10, which encodes the catalytic subunit of the N-terminal acetyltransferase A (NatA) complex. The auxiliary subunit of the NatA complex, NAA15, is the dimeric binding partner for NAA10. Through a genotype-first approach with whole-exome or genome sequencing (WES/WGS) and targeted sequencing analysis, we identified and phenotypically characterized 38 individuals from 33 unrelated families with 25 different de novo or inherited, dominantly acting likely gene disrupting (LGD) variants in NAA15. Clinical features of affected individuals with LGD variants in NAA15 include variable levels of intellectual disability, delayed speech and motor milestones, and autism spectrum disorder. Additionally, mild craniofacial dysmorphology, congenital cardiac anomalies, and seizures are present in some subjects. RNA analysis in cell lines from two individuals showed degradation of the transcripts with LGD variants, probably as a result of nonsense-mediated decay. Functional assays in yeast confirmed a deleterious effect for two of the LGD variants in NAA15. Further supporting a mechanism of haploinsufficiency, individuals with copy-number variant (CNV) deletions involving NAA15 and surrounding genes can present with mild intellectual disability, mild dysmorphic features, motor delays, and decreased growth. We propose that defects in NatA-mediated N-terminal acetylation (NTA) lead to variable levels of neurodevelopmental disorders in humans, supporting the importance of the NatA complex in normal human development.
