Susceptibility genes for age-related maculopathy (ARM) on chromosome 10q26
View Patent ↗Allelic variations in the genes PLEKHA1 and LOC387715 are identified herein as risk factor for Age Related Maculopathy (ARM). A method is therefore provided for identifying a risk of development of ARM in an individual that comprises identification of allelic variations in PLEKHA1 and/or LOC387715. Related apparatus, such as an array, are identified as being useful in implementing those methods.
1. A method of determining risk of developing severe Age-Related Maculopathy in a human subject comprising detecting the presence of a thymine or guanine at base 270 of SEQ ID NO: 20 (rs 10490924) from a sample obtained from the subject, wherein the presence of thymine for one or both alleles indicates increased risk of developing severe Age-Related Maculopathy and the presence of guanine for both alleles indicates decreased risk of developing severe Age-Related Maculopathy.
2. The method of claim 1 further comprising examining one or more allelic variations in one or more of PLEKHAI, PRSS11 and LOC387715.
3. The method of claim 1 in which the patient has one or more symptoms of Age-related Maculopathy and the presence of thymine—for one or both alleles indicates increased risk of developing end-stage Age-Related Maculopathy and the presence of guanine for both alleles indicates decreased risk of developing end-stage Age-Related Maculopathy.
4. The method of claim 3 in which the patient has one or more symptoms of Age-related Maculopathy and the presence of thymine for one or both alleles indicates increased risk of developing one or both of geographic atrophy and choroidal neovascular membranes and the presence of guanine for both alleles indicates decreased risk of developing one or both of geographic atrophy and choroidal neovascular membranes.
5. The method of claim 1 in which the presence of thymine for one or both alleles indicates increased risk of developing end-stage Age-Related Maculopathy and the presence of guanine for both alleles indicates decreased risk of developing end-stage Age-Related Maculopathy.
6. The method of claim 5 in which the presence of thymine for one or both alleles indicates increased risk of developing one or both of geographic atrophy and choroidal neovascular membranes and the presence of guanine for both alleles indicates decreased risk of developing one or both of geographic atrophy and choroidal neovascular membranes.
