miRNA expression data from xlpra2 and normal canine retinas

To identify miRNAs associated with retinal development and degeneration in dogs affected with xlpra2, an early-onset canine retinal degeneration caused by a microdeletion in RPGRORF15. XLPRA2-mutant and normal retinas were selected at different ages for RNA extraction and hybridization on Affymetrix miRNA-specific microarrays. miRNA expression was analysed at three crucial ages for the xlpra2 disease: 3, 7, and 16 wks. Three xlpra2-mutant and four normal retinas (biological replicates) were analysed at both 3 and 16 wks of age, while 4 biological replicates per group (both xlpra2 and normal retinas) were analysed at 7 wks of age.
