SLC25A33 and Abnormal retinal morphology: To demonstrate the use of ChIP-on-chip predictions to find novel gene activation events, four additional genes were selected for quantitative PCR analysis (qRT–PCR analysis); these four genes have human homologs located in unidentified retinal disease regions: Solute carrier family 25 member 33 (Slc25a33), Lysophosphatidylcholine acyltransferase 1 (Lpcat1), Coiled-coil domain-containing 126 (Ccdc126), and ADP-ribosylation factor-like 4D (Arl4d).
