Heritability rate of schizophrenia
Witryna2 sty 2024 · Probandwise concordance rates were calculated for the nuclear syndrome and a heritability estimate was derived from biometric model fitting. Results. Probandwise concordance rates were 13/49 (26.5%) for monozygotic and 0/45 to 2/46 (0.0–4.3%) for dizygotic pairs. The heritability estimate for the best-fitting model was … Witryna15 mar 2024 · The estimated 79% heritability of SZ is congruent with previous reports and indicates a substantial genetic risk. The high genetic risk also applies to a broader phenotype of SZ spectrum disorders. The low concordance rate of 33% in monozygotic twins demonstrates that illness vulnerability is not solely indicated by genetic factors.
