10-18 PCR and Sanger sequencing
PCR (Polymerase chain reaction)
A method for exponentially amplifying the target DNA region by using the fact that DNA dissociates from double-stranded DNA to single-stranded DNA by heating and returns to double-stranded DNA by cooling, binding the target primer to single-stranded DNA as a template, and repeatedly performing DNA synthesis by the transcription reaction of DNA polymerase.
Sanger sequencing
This method uses DNA polymerase, a DNA replication enzyme, to synthesize DNA fragments whose ends correspond to specific bases, and currently uses dideoxynucleotides labeled with four different fluorescent dyes in the elongation reaction. Sequences are determined by using a capillary electrophoresis system to detect the type of fluorescent dye of dye-terminator and the length of DNA fragments, incorporated randomly in the elongation reaction from a single primer that binds specifically to the template DNA.

COMMENT

The test is used to identify patients at high risk for hereditary breast-ovarian carcinoma syndrome (HBOC) among patients with breast, ovarian or fallopian tube carcinoma, and to assist in determining medical management.
Avoid freezing. Please be sure to specify your sex when making your request. Avoid duplicate requests with other items. This testing method can be affected by contamination, so be careful when handling the specimen. The number of days required may vary depending on the measurement and analysis situation.
●What is BRCA1/2 genetic testing?
It is a companion diagnostic used to provide medical professionals with a clinically meaningful variant classification of patients and to assist in determining the indication for olaparib.
*For breast carcinoma only, it is a companion diagnostic used to assist in determining the indication for olaparib and talazoparib tosylate.
