Abstract
A method detects whether an individual is predisposed to obesity. The method includes the steps of (i) obtaining a sample containing human genomic DNA from the individual; (ii) detecting whether the genomic DNA in the sample has a 7 AT tandem repeat in exon 18 of the low density lipoprotein receptor gene on one or both chromosomes; and (iii) correlating the absence of the 7 AT tandem repeat on the chromosome or chromosomes with a predisposition to obesity in the individual.
Claims5
A method for detecting whether an individual is predisposed to obesity, comprising the steps of:
- i) obtaining a sample containing human genomic DNA from said individual,
- ii) detecting whether genomic DNA in said sample has a 7 AT tandem repeat in exon 18 of the low density lipoprotein receptor gene on one or both chromosomes containing said gene, and
- iii) correlating the absence of the 7 AT tandem repeat on said chromosome or chromosomes with a predisposition to obesity in said individual.
A method for detecting whether an individual is predisposed to obesity, comprising the steps of:
- i) obtaining a sample of blood containing human genomic DNA from said individual,
- ii) detecting whether said genomic DNA in said sample has a 7 AT tandem repeat in exon 18 of the low density lipoprotein receptor gene on one or both chromosomes containing said gene by PCR amplification using SEQ ID NO:1 and/or SEQ ID NO:2 as primers and identifying one or more PCR products by electrophoretic separation, and
- iii) correlating the presence of a 106 bp PCR product with a predisposition to leanness in said individual, and correlating the absence of the 106 bp PCR product with a predisposition to obesity in said individual, wherein the presence of the 106 bp PCR product is correlated with the presence of the 7 AT tandem repeat.
A method for detecting whether an individual is predisposed to obesity, comprising the steps of:
- i) obtaining a sample containing human genomic DNA from said individual,
- ii) detecting whether said genomic DNA in said sample has a 7, 8, and/or 10 AT tandem repeat in exon 18 of the low density lipoprotein receptor gene on one or both chromosomes containing said gene, and
- iii) correlating:
- (a) the presence of the 7 AT tandem repeat on both of the chromosomes with a predisposition to leanness in said individual;
- (b) the presence of the 7 AT tandem repeat on one of the chromosomes and the 8 AT tandem repeat on the other chromosome with a predisposition to leanness in said individual;
- (c) the presence of the 7 AT tandem repeat on one of the chromosomes and the 10 AT tandem repeat on the other chromosome with a predisposition to leanness in said individual;
- (d) the presence of the 8 AT tandem repeat on both of the chromosomes with a predisposition to obesity in said individual;
- (e) the presence of the 8 AT tandem repeat on one of the chromosomes and the 10 AT tandem repeat on the other chromosome with a predisposition to obesity in said individual;
- or
- (f) the presence of the 10 AT tandem repeat on both of the chromosomes with a predisposition to obesity in said individual.

- iii) correlating:
- (a) the presence of a 106 bp PCR product with a predisposition to leanness in said individual;
- (b) the presence of only the 106 bp PCR product and a 108 bp PCR product with a predisposition to leanness in said individual;
- (c) the presence of the 106 bp PCR product and a 112 bp PCR product with a predisposition to leanness in said individual;
- (d) the presence of only a 108 bp PCR product with a predisposition to obesity in said individual;
- (e) the presence of the 108 bp PCR product and the 112 bp PCR product with a predisposition to obesity in said individual;
- or
- (f) the presence of only the 112 bp PCR product with a predisposition to obesity in said individual, wherein the presence of the 106 bp PCR product, the 108 bp PCR product, and the 112 bp PCR product are correlated with the presence of the 7 AT tandem repeat, the 8 AT tandem repeat, and the 10 AT tandem repeat, respectively.
