TL;DR
In a population-based twin study of schizophrenia, heritability was estimated at 83%, with the remaining variance in liability attributed to environmental factors not shared in common among co-twins.
Abstract
In a population-based twin study of schizophrenia, heritability was estimated at 83%, with the remaining variance in liability attributed to environmental factors not shared in common among co-twins. Despite the notable limitation of using diagnoses ascertained through treatment contacts, the heritability estimate in this study is almost identical to those reported in recent studies of index pairs using standardized applications of DSM-III or later criteria.

Reliability of LTH of MD was modest, and was predicted by the number of depressive symptoms, treatment seeking, number of episodes, and degree of impairment, and from an "index of caseness" from these predictors, the estimated heritability was greater for more restrictive definitions.
