Table 2.
Gene(s) | Mutations | Number of observed mutations | Number of expected mutations | p value |
---|---|---|---|---|
SMAD6 | Loss of function | 2 | 0.00026 | 3.31 × 10−8 |
SMAD6 | Missense | 1 | 0.0046 | 4.67 × 10−3 |
SPRY1, SPRY2, SPRY3, SPRY4 | Nonsense, splice site, frameshift | 2 | 0.001193 | 7.11 × 10−7 |
Probabilities calculated from the Poisson distribution using DenovolyzeR. The probability of observing at least 2 LOF and 1 missense mutation in SMAD6 was 3.6 ×10−9 via Fisher’s method.
