Figure 1. Properties of the Multiplicity Test.

Figure 1

(A) The probability a risk gene has two or more de novo LoF mutations in Inline graphic families (i.e., the power) depends on the mutation rate Inline graphic. Power per gene of the Multiplicity Test as a function of Inline graphic is shown for 4 mutation rates, which were chosen based on percentiles (25'th, 50'th, 75'th, 90'th) of the distribution of Inline graphic obtained from the full gene set. (B) The expected number of risk genes discovered by the Multiplicity Test at Inline graphic (red, solid) or 3 (blue, dashed) as a function of the sample size Inline graphic. The barplot shows the FDR at Inline graphic. The simulation assumes 1000 diseases genes out of 18,000, each with relative risk Inline graphic; these parameters were estimated in the section on Genetic Architecture of ASD.
