Previous studies have reported that some variants in crystallin genes (e.g., CRYBB1, CRYBB2, CRYAA, and CRYGC) could lead to a combined occurrence of CC and other ocular abnormalities, such as microcornea, microphthalmia, coloboma, and glaucoma [6, 8]. The gene discussed is CRYBB2; the disease is Microcornea.
