Case #1Imaging / Fetal medicine / Clinical genetics

📋 Case data

Lethality prediction (FL/AC, thorax) + typingShort long bones but FL/AC ≥0.16, normal thoracic circumference (possibly non-lethal)

Data is taken from this pathway's reviewed node text. Work through the pathway step by step.

Step 1 / 1 · Lethality prediction (FL/AC, thorax) + typing

Lethality prediction (FL/AC, thorax) + feature typing?

💡 >450 types, few lethal; lethality is mostly from a small chest → pulmonary hypoplasia. First judge lethality, then find features to type. Measure the true femur length (do not measure end-to-end if bowed).
