Pathogenic variants, particularly in genes involved in the regulation of epigenetic processes and chromatin structure, can result in a very specific, genome-wide methylation profile that differs significantly from the methylation profile in control cohorts. This specific profile is referred to as an epigenetic signature.
When is epigenetic signature analysis useful?
- if there is a strong suspicion of a (syndromic) developmental disorder, but the exome analysis was inconclusive
- if there is an unclear sequence variant in a gene for which a specific epigenetic signature is known
