Scientists at the Reproductive Health Technology Center of the Guangdong Family Planning Research Institute have discovered 39 cases of abnormal chromosomal patterns, previously unidentified anywhere in the world. According to the center’s director, Zheng Lixin, these cases have been validated by the National Medical Genetics Laboratory in Hunan Province.
Chinese scientists have revealed for the first time globally: these new findings follow the analysis of 5,000 blood samples since 1996, which uncovered 1,838 cases of abnormal chromosomal patterns.

One of these cases involves a 4-year-old girl who lost her ability to inherit due to retinoblastoma suppression leading to cancer.
Another case featured a 22-year-old female patient who was born without a uterus.
Tests revealed that an abnormal chromosomal pattern resulted in the loss of a critical gene responsible for uterine formation in this woman.
Scientists also discovered an abnormal chromosomal pattern that caused low sperm counts in a pair of male twins. These conditions currently lack effective treatment options.
Doctors who are well aware of the abnormalities in their patients can offer clinical advice. For example, they may suggest artificial insemination or adoption to avoid the birth of children with disabilities. These new findings will aid scientists in the fields of genetics and cloning.
Abnormal chromosomal patterns may also have applications in chemical, radiation, or biological virus fields.
