Achondrogenesis, type II (ACG2; MIM 200610) and Hypochondrogenesis (MIM 200610) are lethal conditions caused by defects in COL2A1. Although they share phenotypic characteristics, ACG2 is considered more severe. Affected fetuses and infants have a large head, soft cranium, flat face, barrel shaped trunk, and short long bones. In ACG2 the entire spine and sacrum may not be ossified.read more
