1-14. (canceled)
A method of preparing an MECP2 amplified fraction from a subject useful for analyzing an MECP2E1 gene involved in neuropsychiatric or developmental disorder, comprising:
- (a) extracting nucleic acids comprising an MECP2E1 gene from a sample from the subject;
- (b) producing an MECP2E1 amplified fraction of the nucleic acids extracted in (a) by contacting the nucleic acids extracted in (a) with primers to amplify the MECP2E1 gene, wherein the MECP2E1 amplified fraction comprises MECP2E1 amplified products;
- and
- (c) analyzing the MECP2E1 amplified fraction produced in (b).
A method of detecting a mutation in the human MECP2 gene, comprising:
- (a) contacting an MECP2 nucleic acid in a human sample with a labeled oligonucleotide that hybridizes under stringent conditions to the sequence portion within the MECP2 nucleic acid comprising the mutation;
- and (b) detecting the hybridization of the labeled oligonucleotide with the MECP2 nucleic acid under stringent hybridization conditions, wherein detection of hybridization indicates that the mutation is present in the MECP2 nucleic acid;
- wherein the mutation is selected from the group consisting of:
- (i) a deletion of the nucleotide sequence GC at nucleotides −38 and −39 upstream of a position corresponding to nucleotide 1 of SEQ ID NO. 1;
- and (ii) a deletion of the nucleotide sequence AG at nucleotides −19 and −20 upstream of a position corresponding to nucleotide 1 of SEQ ID NO. 1.
A method of detecting the presence of a mutation or deletion in a nucleic acid molecule encoding the MeCP2E1 protein comprising:
- a) analyzing a test sample containing a nucleic acid sequence encoding the MeCP2E1 protein consisting of SEQ ID NO.:
- 4 for a mutation or deletion within exon 1, or in the intron-exon boundary immediately adjacent to exon 1, of the nucleic acid sequence;
- and b) comparing the results of the analysis of the test sample with the results of analysis of a control sample, wherein the control sample comprises the nucleic acid encoding the MeCP2E1 protein consisting of SEQ ID NO.:
- 4 without a mutation or deletion within exon 1, or in the intron-exon boundary immediately adjacent to exon 1.
