In the realm of whole exome sequencing, two additional genes associated with primary congenital glaucoma have been identified - TEK receptor tyrosine kinase/tyrosine kinase with immunoglobulin-like and EGF-like domains 2 (TEK/TIE2) on 9p21.2 and angiopoietin 1 (ANGPT1) on 8q23.1. Here, TEK is linked to primary congenital glaucoma.
