Abstract
Structured
Objectives
To examine the potential role of next‐generation sequencing (NGS) and genetic testing to guide preventive care in dental enamel disorders using publicly available databases to access the frequency of deleterious alleles in AMTN, AMLEX and ENAM, associated with amelogenesis imperfecta (AI).
Setting and Sample Population
Public resources, including gnomAD (The Broad Institute) and the Center for Pediatric Genomic Medicine's warehouse, which together contain variants from nearly 145 000 exomes and genomes.
Material & Methods
Public resources, including sequencing data from ~145 000 exomes and genomes were queried for predicted loss of function variants with a minor allele frequency <1% in AMTN, AMLEX and ENAM.
Results
A total of 95 variants were identified in the combined dataset. If confirmed, this could be diagnostic for autosomal dominant AI.
Conclusions
The rapid integration of NGS into clinical care allows for the expansion of genetic testing for disorders that are not currently tested routinely, including non‐syndromic dental enamel disorders. A genotypic‐driven diagnosis of a disorder of enamel development could impact dental care, especially in young children, including early and more frequent monitoring to prevent complications. As new gene‐disease associations continue to emerge, including those for common and non‐syndromic craniofacial disorders, the possibility of genomic‐guided precision medicine and dentistry and the development of targeted, individualized therapeutics into standard clinical care will increase substantially.
