The new analysis, being published Friday in the journal Science, detected extremely rare and unknown mutations that turned up three to four times as often in people with schizophrenia as in those without it.
Transcriptome sequencing analysis, also known as RNA-seq, has been used in cancer research for the detection of transcribed mutations and confirmation of known and unknown mutations.
We describe here the polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) assay for detecting unknown mutations of the β-globin genes.
First, the model usually takes as a starting point variation in morphology caused by anonymous, unknown mutations, and therefore does not inquire as to what molecular changes might have been responsible for the origins of variation.
A standard group of 15 samples with previously known DNA sequences and a test group of 37 HPA patients with unknown mutations were used for assay validation and application, respectively.
Demeke and co-workers (Demeke et al. [2013b]) reported that the diverse and complex paths followed during the development of GSE16 included unknown mutations that appeared to be linked to the high capacity of the strain to ferment xylose, but that such mutations could also be correlated with a possible detrimental effect in terms of inhibitor tolerance (Demeke et al. [2013b]).
However, once primers and conditions are chosen, TGGE/DGGE is a robust and easy to perform mutation screening method particularly well suited for the detection of known and unknown mutations in large genes, where high sensitivity is required and when large numbers of samples are to be tested.
These results demonstrate that TaqMan probe-based FMCA with color multiplexing can be directly used to scan the existence of unknown mutations within the amplicon.
In addition, unknown mutations can be scanned with FMCA by using a series of single-labeled probes complementary to the wild-type sequence [8].
However, the complex I defect in such patients can be possibly because of some unknown mutations in nuclear genes encoding OXPHOS proteins and assembly factors.
This approach was used to obtain RB51, a B. abortus R mutant that carries a IS711-disrupted wboA (putative glycosyltranferase gene) as well as unknown mutations also affecting LPS.
