Method of screening for LRRK2-related parkinsonism inheritance
View Patent ↗A polynucleotide consisting of the base sequence of SEQ ID NO: 2, or a complementary strand thereto, wherein the X is one of the group being defined by the bases A, C or T. A primer and a probe specific for that polynucleotide, wherein the primer and/or probe contains at the least 10 consecutive nucleotides, and finally use of the probe for proving parkinsonism inheritance.
1. A method for classifying a human subject as having or not having LRRK2-related Parkinsonism inheritance, comprising
determining whether the human subject to be screened for Parkinsonism inheritance comprises a LRRK2 polynucleotide having a G or an A at the position corresponding to position 6055 of SEQ ID NO:2, wherein said determining comprises amplifying DNA from said subject and sequencing said amplified DNA to determine whether a G or an A is present at the position corresponding to position 6055 of SEQ ID NO:2, and
classifying said subject as having LRRK2-related Parkinsonism inheritance if said subject comprises an A at the position corresponding to position 6055 of SEQ ID NO:2, or classifying said subject as not having LRRK2-related Parkinsonism inheritance if said subject comprises a G at the position corresponding to position 6055 of SEQ ID NO:2.
2. The method of claim 1 , wherein said DNA amplified from said subject is from the blood of said subject.
3. A method for classifying a human subject as having or not having LRRK2-related Parkinsonism inheritance, comprising:
(a) contacting DNA amplified from the human subject with a DNA probe specific for a polynucleotide having the sequence of SEQ ID NO:2 or the complement of SEQ ID NO:2, wherein said probe contains more than ten consecutive nucleotides from SEQ ID NO:2 or from the complement thereof, wherein said probe contains nucleotide position 6055 of SEQ ID NO:2 or the corresponding position of the complement of SEQ ID NO:2, and wherein the ability of said probe to hybridize to said amplified DNA indicates whether said subject has an A or a G at position 6055 of SEQ ID NO:2 or a T or a C at the position corresponding to the complement of position 6055 of SEQ ID NO:2; and
(b) based on said hybridization, classifying said human subject as having LRRK2-related Parkinsonism inheritance if said DNA amplified from said subject has an A at position 6055 of SEQ ID NO:2 or a T at the position corresponding to the complement of position 6055 of SEQ ID NO:2, and classifying said human subject as not having LRRK2-related Parkinsonism inheritance if said DNA amplified from said subject has a G at position 6055 of SEQ ID NO:2 or a C at the position corresponding to the complement of position 6055 of SEQ ID NO:2.
4. The method of claim 3 , wherein said DNA is obtained by amplification of DNA from the subject's blood.
5. A method for determining whether a human subject has Parkinsonism inheritance, comprising providing a DNA sample from said subject, and assaying said sample to determine whether said sample comprises a polynucleotide corresponding to SEQ ID NO:2, with the proviso that said polynucleotide comprises an A at the position corresponding to position 6055 of SEQ ID ON:2, wherein the presence of an A at the position corresponding to position 6055 of SEQ ID NO:2 indicates Parkinsonism inheritance.
6. The method of claim 5 , comprising diagnosing said subject as having Parkinsonism inheritance if said polynucleotide comprises an A at position 6055 of SEQ ID NO:2.
7. The method of claim 5 , wherein said sample is a blood sample.
