However, their significance in specific fetal disease contexts remains poorly understood. Anecdotally, placentas belonging to fetuses with skeletal dysplasias (SD) often demonstrate increased placental calcifications. Our aim was to systematically evaluate calcification patterns in SD placentas.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Retrospective case-control study of molecularly confirmed SD placentas (2016-2025) and controls.
