Abstract: A fractional concentration of fetal relevant DNA in a mixture of DNA from a biological sample is determined based on amounts of DNA fragments of a particular size or range of sizes. DNA fragments may be sequenced to obtain sequence reads, and the sequence reads may be aligned to a reference genome to determine sizes of the DNA fragments. Calibration data points (e.g., as a calibration function) indicate a correspondence between values of a parameter providing a statistical measure of a size profile and the fractional concentration of the fetal DNA. For a given sample, a value of the parameter can be determined from DNA fragments of a particular size or range of sizes in a sample. A comparison of the value to the calibration data points can provide the estimate of the fractional concentration of the fetal DNA.
