WebMay 1, 2014 · Truncating variants, which have a more deleterious impact on gene products, are often pathogenic to diseases that are caused by loss-of-function gene products. Nontruncating variants can result in loss of function or gain of function, and it is often more difficult to predict their pathogenicity. WebFeb 1, 2016 · Disease may be caused by direct changes in epigenetic marks, such as DNA methylation, commonly found to affect imprinted gene regulation. Also described are disease-causing genetic mutations in epigenetic modifiers that either affect chromatin in trans or have a cis effect in altering chromatin configuration. WebThe gene that shows a mutation among the affected individuals would be the disease-causing gene.
