Mutations in the TMCO3 Gene are Associated with Cornea Guttata and Anterior Polar Cataract.

ABSTRACT: The molecular basis for cornea guttata and anterior polar cataract remains idiopathic in most cases. In this study, our aim was to identify the disease-associated gene in Chinese patients with these conditions. Patients with the conditions from two Chinese families, and ten sporadic patients, were investigated. Genome-wide linkage and exome sequencing analyses showed transmembrane and coiled-coil domain 3 (TMCO3) as the disease candidate gene for a coding heterozygous mutation c.41C > T, resulting in a P14L amino acid change that co-segregated with the disease phenotype as discovered in Family A. TMCO3 belongs to the monovalent cation: protein antiporter 2 transporter family, a moderately large group whose members all share a very similar function under normal physiological conditions. The
