Genomic sequence of the 5-Lipoxygenase-activating protein (FLAP), polymorphic markers thereof and methods for detection of asthma
View Patent ↗The invention concerns the genomic sequence of the FLAP gene. The invention also concerns biallelic markers of a FLAP gene and the association established between these markers and diseases involving the leukotriene pathway such as asthma. The invention provides means to determine the predisposition of individuals to diseases involving the leukotriene pathway as well as means for the diagnosis of such diseases and for the prognosis/detection of an eventual treatment response to agents acting on the leukotriene pathway.
1. A method of determining whether an individual is at risk of developing asthma comprising the steps of:
(a) obtaining a biological sample comprising a nucleic acid from said individual;
(b) determining the identity of a biallelic marker at position 16347 of SEQ ID NO: 1 and 28368 of SEQ ID NO: 1 within said biological sample; and
(c) evaluating whether an individual is at increased risk of asthma; wherein the presence of both an A at position 16347 of SEQ ID NO: 1 and a T at position 28368 of SEQ ID NO: 1 is indicative of an increased risk for developing asthma.
2. The method according to claim 1 , further comprising the step of amplifying a portion of the FLAP gene comprising said biallelic marker prior to determining the identity of said nucleotide.
3. The method according to claim 1 , wherein said amplifying is performed by PCR.
4. The method according to claim 1 , wherein said nucleotide is determined by performing a microsequencing assay.
5. The method according to claim 1 , wherein said nucleotide is determined by performing a hybridization assay.
6. The method according to claim 1 , wherein said nucleotide is determined by performing a sequencing assay.
