Odds Ratio (OR) and p values are given from a Cochran-Mantel-Haenszel exact test. No gene reached study-wide significance (p < of 2.9 × 10−7). The accompanying homogeneity p value indicates the lowest p value from Breslow-Day & Woolf tests for homogeneity of odds, where p values < 0.05 indicate significantly different odds between the two analysis datasets. CI: Confidence Interval. HGNC: HUGO (Human Genome Organization) Gene Nomenclature Committee gene names. QVs: qualifying variants. URVs: Ultra-rare Variants. See Table 1 for the details of the PPh2, REVEL & MTR analysis models.
