© 2016 Elsevier Ltd.Night eating syndrome (NES) represents a circadian delay in the pattern of eating. As there are genetic links for other eating- and circadian-based disorders, it is likely that there is a genetic basis for NES as well. We present a family case study of three identified patients and their extensive family history of NES and co-morbid mood disorders. This case report suggested that NES may have a heritable feature, particularly nocturnal ingestions. Of the seven identified cases, four had co-morbid mood disorders, and all descended from a couple with bipolar disorder and delusional disorder. More work is needed to understand the extent of genetic influence on NES, and the relationship between NES and other psychiatric disorders.
