Fig. 2From: Analysis of the VSX1 gene in sporadic keratoconus patients from ChinaThe p.Arg131Pro variant of the VSX1 gene. The sequence of a normal control (a) included the nucleotides CGC at codon 131 in exon 1 of VSX1. The missense variant sequence (b) showed a G to C (c. 5427 G > C) heterozygous transition at the second nucleotide position in this codon (arrow), which results in a change from arginine (CGC) to proline (CCC) (p.Arg131Pro)Back to article page
