Fig. 2: Protein–protein interactions predicted for proteins affected by pathogenic de novo mutations.

Significantly larger number of interactions were observed in proteins affected by de novo mutations than expected for a similar sized dataset of randomly selected proteins (PPI enrichment p value = 2.35 × 10−2). The central module of the main interaction network (blue dashed circle) contains 5 proteins involved in mRNA splicing (Supplementary Fig. 6).
