Tumours in these mice grew 50 per cent more slowly than those in healthy mice, indicating that one extra
copy of the
gene has a
significant effect on tumour growth (Nature, DOI: 10.1038 / nature08062).
By performing a meta - analysis of rare coding variants in whole - exome sequences from 4,133 schizophrenia cases and 9,274 controls, de novo mutations in 1,077 family trios, and
copy number variants from 6,882 cases and 11,255 controls, we show that individuals with schizophrenia carry a
significant burden of rare, damaging variants in 3,488
genes previously identified as having a near - complete depletion of loss - of - function variants.
