A pioneer test to identify chromosomal abnormalities
Infertility affects 1 in 6 couples locally and globally. Among them, recurrent miscarriages (RM) carry psychological and financial burdens for the affected couples. However, the aetiology of RM remains uncertain and leaves a management challenge for counselling and treatment. The team pioneered a genome-sequencing-based test for prenatal invasive genetic diagnosis in 2019. In 2020, they introduced an advanced version of the test to precisely identify RM-related chromosomal abnormalities. This new approach provided a comprehensive detection of the RM-related genetic defects with a significant increased diagnostic yield.
