In addition to disease-causing variation in the FGFR3 (n = 8), COL2A1 (n = 7), COL1A1 (n = 8), and COL1A2 (n = 6) genes, fetal molecular diagnoses were also more common in the DYNC2H1 (n = 3) and SOX9 (n = 3) genes associated with autosomal recessive short-rib thoracic dysplasia (MIM 613091) and campomelic dysplasia (MIM 114290), respectively. The gene discussed is COL2A1; the disease is campomelic dysplasia.
