Genomic risk profiling in advanced maternal age: a Tamil Nadu prenatal study

2026-08-28

Abstract excerpt

Background Advanced maternal age (AMA; > = 35 years) is associated with increased fetal chromosomal risk and is an important indication for invasive prenatal diagnosis. This study evaluates karyotyping and chromosomal microarray analysis (CMA) findings among AMA pregnancies in Tamil Nadu, India. Methods In this prospective observational study, 2,200 pregnant women aged ≥35 years who underwent amniocentesis between...
