Table 3. Amino acid variation in Gag p17 and p24 associated with HLA-B*57/58:01 disease progression.
AA | Comparison | AA variation*** | ||||
Position | SH | Progressors | LTNPs | |||
SH value* | Z score** | Dominant | Minor | Dominant | Minor | |
S126 | 0.83 | −10.7 | SK | N | S | N |
L215 | 0.61 | −27.8 | LT | I | L | M |
*The Sequence Harmony (SH) score represents overlap in amino acid composition between the two groups analyzed (HLA-B*57/58:01 progressors versus HLA-B*57/58:01 LTNPs). An SH value of 0 indicates no overlap (largest possible differences) while a value of 1 indicates complete overlap (no differences).
**All Z scores represent P values <0.0001 with correction for multiple testing (450 alignment positions).
***The most frequent amino acids found at a certain position are depicted as “Dominant”, whereas the “Minor” amino acids are present at least 2 times less frequent than the most frequently occurring amino acid at this position. Amino acids are ordered from highest to lowest frequency.
