Taste sensitivity to phenylthiocarbamide in a sample of Hungarian Gipsies.

: PTC sensitivity in Gipsy and non-Gipsy populations of Hungary was evaluated. A significantly high difference was observed between the proportions of non-tasters among the Gipsies (39.3 per cent) and the non-Gipsies (26.4 per cent). These results are regarded as a probable confirmation of the Indian origin of the Gipsies, as the percentage of non-tasters in the majority of the different Indian tribes is higher than that of the European populations.
