V518 (= V33) to I: in allele TAP1*x; dbSNP:rs41561219
S545 (= S60) binding
D637 (= D152) to G: in allele TAP1*02:01, allele TAP1*04:01 and allele TAP1*x; dbSNP:rs1135216
R648 (≠ K163) to Q: in allele TAP1*04:01; dbSNP:rs1057149
R659 (≠ I174) to Q: in a lung cancer cell line deficient in MHC class I presentation; dbSNP:rs121917702
D674 (vs. gap) mutation to A: Impairs allosteric coupling of peptide transport to ATP hydrolysis, converting the unidirectional active pump into a passive bidirectional nucleotide-gated facilitator. Inactive in peptide transport when associated with 'A-638' of TAP2.

Sites not aligning to the query:

7 P → S: in dbSNP:rs375389015
17 G → R: in dbSNP:rs57640466
32 Inter-subunit salt bridge with TAPBP; D→K: Complete loss of interaction with TAPBP, resulting in impaired PLC assembly and antigen presentation.
