Table 7 Distribution of HL symmetry in GJB2(+) and GJB2(−) subgroups

From: The high frequency of GJB2 gene mutation c.313_326del14 suggests its possible origin in ancestors of Lithuanian population

  Non symmetric Symmetric Total
GJB2 (−) 10 47 57
GJB2 (+) 7 77 84
Total 17 124 141
Pearson Chi-Square 2.7 p = 0.099
Empirical effect size w = 0.3 Empirical power = 0.9
