We observed Heph expression in the renal cortex of SCD and control mice by real-time RT-PCR, but there was no difference in the expression levels between SCD and control mice (Supplemental Figure S3, Heph-Actb delta Ct, −5.059 ± 0.22 in SCD vs. −5.61 ± 0.23 in control, p = 0.1067). This evidence concerns the gene HEPH and Schnyder corneal dystrophy.
