NAA10-related syndrome.

Area of Science:

• Genetics and Molecular Biology
• Human Physiology
• Developmental Biology

Background:

• NAA10-related syndrome is an X-linked disorder with a wide range of clinical presentations.
• Phenotypes vary from severe in males with specific NAA10 variants (Ogden syndrome) to milder intellectual disability in both sexes with other variants.

Purpose of the Study:

• To provide a comprehensive overview of NAA10-related syndrome.
• To emphasize the broad phenotypic variability and the need for unified nomenclature.
• To review the current understanding of the mechanistic basis for NAA10-related phenotypes.

Main Methods:

• Literature review of clinical and genetic studies on NAA10-related conditions.
• Analysis of reported phenotypes associated with different NAA10 variants.
• Discussion of the proposed functions of the NAA10 enzyme in protein acetylation.

Main Results:

• NAA10-related syndrome exhibits significant phenotypic heterogeneity, including intellectual disability, developmental impairments, cardiovascular anomalies, growth disturbances, and dysmorphic features.
• The severity and specific findings depend on the type and location of the NAA10 gene variant.
• The NAA10 enzyme's role in N-terminal protein acetylation is established, but its precise contribution to the syndrome's pathology is under investigation.

Conclusions:

• NAA10-related syndrome is a clinically diverse group of disorders.
• A unified designation, NAA10-related syndrome, is proposed to encompass the spectrum of conditions.
• Further research is needed to elucidate the molecular mechanisms linking NAA10 variants to human phenotypes.
