With an impressive portfolio of 26 patents, she has made significant strides in enhancing the accuracy and efficiency of prenatal diagnostics. Her work is pivotal in providing expecting parents with critical information about fetal health without the risks associated with invasive procedures.

Latest Patents

Among her latest innovations, Fan has developed a method for the noninvasive diagnosis of fetal aneuploidy through advanced sequencing techniques. This method employs digital quantification of DNA by counting differences between identical sequences using direct shotgun sequencing. The process is further enhanced by massively parallel sequencing, which generates millions of short sequence tags in a single run, allowing for a comprehensive statistical evaluation of the sample.

Another notable patent involves noninvasive fetal genetic screening utilizing digital analysis. This method processes maternal blood containing fetal DNA, diluted to approximately 0.5 genome equivalents per reaction sample. Digital amplification enables the detection of aneuploidies, such as trisomy 21 which causes Down Syndrome, without resorting to invasive techniques like amniocentesis. This innovative approach examines tens of thousands of genome equivalents to ensure accurate results.
