TABLE 1.

Summary of SSCP screen of human TLR2 in a population of healthy blood donors (Iowa)^a

Nucleotide change	Amino acid	Conservedb	Frequency (out of 110)
C597T	Silent	NA	3
T1350C	Silent	NA	3
G2258A	Arg–Gln	Yes	3

^aIn addition to the Arg753Q polymorphism, two silent polymorphisms were detected in the SSCP screen of 110 healthy blood donors. Each silent mutation was found in three patients. Aberrant bands were sequenced to verify the nucleotide change.
