Table 2 Percentage of embryos (sides) examined with cranial nerve abnormalities

From: Nav2 is necessary for cranial nerve development and blood pressure regulation

Genotype Phenotype 1: gIX weakly or not connected to hindbrain Phenotype 2: CN IX/X fusion Phenotypes 1 and 2 combined
Wild type 7% (4/59) 7% (4/59) 14% (8/59)
Homozygote 27% (72/266) 17% (45/266) 44% (117/266)
  1. Values shown in parentheses are the number of abnormal observations over the total number of observations (60 wild-type and 133 homozygous embryos were scored on both the right and left side; one wild-type side (observation) was lost). Phenotype 1: Z-score = -3.33 and P-value ≤ 0.001. Phenotype 2: Z-score = -1.97 and P-value ≤ 0.05. Phenotypes 1 and 2 combined: Z-score = -4.35; P-value ≤ 0.0001. gIX, ganglia IX.
