Abstract

The invention discloses a data processing method and device, a storage medium and a processor. The method includes: acquiring gene sequence on sample chromosome; comparing the gene sequence with humangenome reference sequence, and determining unique base sequence reads, matched with the human genome reference sequence, in the sample chromosome; statistically counting the number of base sequence reads in each observation area bin, wherein the observation areas bin are obtained by performing window separation on the sample chromosome according to preset window separation conditions; determininga hidden Markov model according to the number of the base sequence reads in the multiple observation areas bin; determining gene copy number variation CNV according to the hidden Markov model, wherein the copy number variation CNV comprises at least one observation area bin. By the method, the technical problem that interference factors in chromosome abnormality diagnosis cannot be determined inthe prior art is solved.

Description

technical field [0001] The present invention relates to the field of biology, in particular to a data processing method, device, storage medium and processor. Background technique [0002] Chromosomal abnormalities are an important cause of birth defects. Among many chromosomal abnormalities, fetal chromosomal aneuploidy is the most common chromosomal abnormality in fetuses. Therefore, prenatal diagnosis can diagnose the fetus in the first or second trimester for early intervention or treatment, which is an important means to reduce birth defects and improve the quality of the birth population. [0003] At present, prenatal diagnosis of chromosomal abnormalities is usually divided into non-invasive and invasive methods. Invasive methods include: chorionic villi biopsy, amniocentesis, and transabdominal umbilical vein puncture, among others. Although the diagnostic results of invasive methods are more accurate, they are quite risky and can easily cause miscarriage or intrau...
