Methods and compositions for screening and treating developmental disorders
This document provides methods and materials related to genetic variations of developmental disorders. For example, this document provides methods for using such genetic variations to assess susceptibility of developing Autism Spectrum Disorder.
1. A method of hybridizing a nucleic acid probe comprising:
(a) hybridizing the nucleic acid probe to a polynucleic acid from a human subject by nucleic acid hybridization or microarray analysis, wherein the human subject has Autism Spectrum Disorder; and
(b) detecting a genetic variation in the polynucleic acid by the nucleic acid hybridization or microarray analysis, wherein the genetic variation is a CNV, wherein the CNV is the loss of SEQ ID NO 592, SEQ ID NO 593, or the complements thereof, in the ATXN2 gene.
2. A method of synthesizing a nucleic acid product comprising:
(a) synthesizing the nucleic acid product from a polynucleic acid from a human subject by PCR or sequencing, wherein the human subject has Autism Spectrum Disorder; and
(b) detecting a genetic variation in the polynucleic acid by the PCR or sequencing, wherein the genetic variation is a CNV, wherein the CNV is the loss of SEQ ID NO 592, SEQ ID NO 593, or the complements thereof, in the ATXN2 gene.
3. The method of claim 1 or 2 , wherein the CNV is loss of SEQ ID NO: 593 or the complement thereof.
4. The method of claim 2 , wherein the nucleic acid product synthesized from the polynucleic acid is cDNA.
5. The method of claim 1 or 2 , wherein the polynucleic acid comprises a nucleic acid from blood, saliva, urine, serum, tears, skin, tissue, or hair from the human subject.
6. The method of claim 1 or 2 further comprising purifying the polynucleic acid.
7. The method of claim 1 , wherein the microarray analysis is selected from the group consisting of a Comparative Genomic Hybridization (CGH) array analysis and an SNP array analysis.
8. The method of claim 2 , wherein the sequencing is a high-throughput sequencing method.
9. The method of claim 1 or 2 , wherein the whole genome or whole exome of the subject is analyzed.
10. The method of claim 1 or 2 , wherein the CNV is loss of SEQ ID NO: 592 or the complement thereof.
