Although the abstract by Giangrieco et al. (Maria Antonietta Ciardello) indicates that a few of the tomato allergic subjects were monosensitized to Sola l 6, they must have meant monosensitized to LTP as a number had as much or higher IgE to other LTPs and even those with high IgE to the 7kD tomato LTP had high IgE to at least one other species LTP based on table 2 of the Mol. Immunology paper.

A second group, Mayte Villalba et al., from Madrid has submitted the same sequence, but a full-length sequence for a name for this LTP to IUIS prior to the Giangrieco entry, but with incomplete information. They presented at a Spanish Congress XXXVII SEBBM at Granada, Spain abstr P06r-2, in 2014. They claim 16 of 28 tomato allergic subjects had IgE binding by Western and ELISA, 5 of 7 were SPT+ and 5 of 7 were positive by BAT. They claim to have had 69% coverage of the cited full-length sequence of EST referenced by Giangrieco, XP_004232333. Both groups (L. Martin-Pedraza et al., and Giangrieco et al., deserve to be recognized for their contributions.
