Table 3 Seven variants of CagL in GC and non-GC isolates without 5 Vietnamese isolates

From: Genetic variants of Helicobacter pylori type IV secretion system components CagL and CagI and their association with clinical outcomes

Residue Reference Variant GC (n = 5) (%) non-GC (n = 30) (%) p value (GC versus non-GC)
59 Glu Lys 1 20.0 25 83.3 <0.05
88 Ala Thr 1 20.0 0 0.0 NS
101 Lys   0 0 0 0 ND
141 Gly   0 0 0 0 ND
142 Lys   0 0 0 0 ND
201 Asn Asp 3 60.0 24 80.0 NS
234 Ile Val 2 40.0 23 76.7 NS
  1. Statistical analysis was performed by Fisher’s exact test. Residue 234 is a part of the C-terminal motif in the distal six amino acids of CagL
  2. GC gastric cancer, NS not significant, ND not determined
