1. A method of screening for a human individual'"'"'s predisposition to atopy, the method comprising:
- analyzing said individual for the presence of an INS157 polymorphism in TIM-1 by contacting a biological sample comprising DNA or mRNA from such individual with a probe that specifically binds to the nucleic acid sequence ATGACAACGACTGTTCCA, SEQ ID NO;
22, bases 472-489, encoding the amino acid sequence MTTTVP, SEQ ID NO;
25, residues 158-163;
detecting the presence of a complex formed between said probe and said genomic DNA, mRNA or a transcript thereof; and
analyzing said individual for the presence of hepatitis A virus (HAV) seropositivity wherein said seropositivity in an individual comprising an allele of TIM-1 comprising the amino acid sequence MTTTVP, SEQ ID NO;
25, residues 158-163 is indicative of a reduced risk of developing atopy.

Abstract
A genetic locus and corresponding family of proteins associated with regulation of immune development, function, and cell survival are provided. The locus comprising the TIM family is genetically associated with immune dysfunction, including atopy, autoimmunity, inflammatory bowel disease, dysplasia, and susceptibility to blood-bourne infectious diseases. Polymorphisms in the human TIM-1 gene and exposure to Hepatitis A Virus (HAV) are shown to be associated with protection from the development of atopy.
