Evaluating genetic disorders
The present invention relates to genetic analysis and evaluation utilizing copy-number variants or polymorphisms. The methods utilize array comparative genomic hybridization and PCR assays to identify the significance of copy number variations in a subject or subject group.
1. A method of hybridizing a nucleic acid probe or synthesizing a nucleic acid product comprising
(a) hybridizing a nucleic acid probe to a polynucleic acid from at least one affected non-human mammalian subject and at least 100 unaffected non-human mammalian subjects by nucleic acid hybridization or microarray analysis, or
synthesizing a nucleic acid product from a polynucleic acid from at least one affected non-human mammalian subject and at least 100 unaffected non-human mammalian subjects by PCR or sequencing;
wherein the at least one affected non-human mammalian subject has a phenotype associated with a disease, and the at least 100 unaffected non-human mammalian subjects do not have the phenotype associated with the disease; and
(b) detecting at least one copy number variation from the at least one affected non-human mammalian subject that has the phenotype associated with the disease that occurs at least once per affected non-human mammalian subject, wherein detecting is detecting by the nucleic acid hybridization, microarray analysis, PCR or sequencing, and wherein a frequency of the copy number variation in the 100 unaffected non-human mammalian subjects was determined.
2. The method of claim 1 , wherein the number of unaffected non-human mammalian subjects is at least 1,000 unaffected non-human mammalian subjects.
3. The method of claim 1 , wherein whole genome or exome of the at least one affected non-human mammalian subject and the at least 100 unaffected non-human mammalian subjects are analyzed.
4. The method of claim 1 , wherein the detecting comprises purifying the polynucleic acid and performing a microarray analysis.
5. The method of claim 1 , wherein the microarray analysis is array Comparative Genomic Hybridization (CGH) analysis.
6. The method of claim 1 , wherein the sequencing is a high-throughput sequencing method.
7. The method of claim 1 , wherein the step (a) further comprises amplifying a junction fragment of the at least one copy number variant.
8. The method of claim 1 , wherein the step (a) comprises hybridizing the nucleic acid probe by microarray analysis.
9. The method of claim 1 , wherein step (a) comprises synthesizing the nucleic acid product by sequencing.
10. The method of claim 1 , wherein the microarray analysis is an SNP array analysis.
11. The method of claim 1 , wherein the number of unaffected non-human mammalian subjects is at least 5,000 unaffected non-human mammalian subjects.
12. The method of claim 1 , wherein the number of unaffected non-human mammalian subjects is at least 10,000 unaffected non-human mammalian subjects.
13. The method of claim 1 , wherein the method comprises determining the breakpoints of the at least one copy number variation.
14. The method of claim 13 , wherein the breakpoints are determined by PCR or microarray.
