Distribution of mutations and phenotypes in the Xia–Gibbs
registry among patients with a frameshift or nonsense variant. AT-hook domains,
PDZ binding domain, and REV3L/NEXMIF (KIAA2022) conservation regions are shown.
Each column in the heatmap represents a patient ranked by the position of the
variant carried by the patient. Only frameshift and nonsense variants were
included in the analysis. Mutations were classified as N-terminal, mid-protein,
and C-terminal based on which one-third of the protein they occurred in,
respectively. Each row represents a clinical phenotype from patient surveys with
rows labeled in red representing phenotypes occurring in more than 80% of
individuals. The phenotypes were ranked by p values of logistic
regression tests for associations between the binary outcome and positions of
all the variants
