Fig. 5From: Analysis of the VSX1 gene in sporadic keratoconus patients from ChinaThe c.8326G > A homozygous change of the VSX1 gene. The sequence of a normal control (a) included the nucleotide G at position 8326 in the third intron of VSX1. The variant sequence (b) showed a G to A homozygous transition (arrow), which results in a c.8326G > A SNP changeBack to article page
