Novel missense COL2A1 variant in a fetus with achondrogenesis type II.
Achondrogenesis type II (ACG2) is a lethal skeletal disorder caused by pathogenic variants in COL2A1. We present a fetus with cystic hygroma and severe shortening of the limbs at 14 weeks of gestation. We performed postnatal genetic analysis of the parents and fetus to diagnose the disease. A novel missense variant of COL2A1 [NM_001844.5: c.2987G>A, (p. Gly996Asp)] was identified, which led to the ACG2 diagnosis.
