The human ortholog of the rodent testis-specific ABC transporter Abca17 is a ubiquitously expressed pseudogene (ABCA17P) and shares a common 5' end with ABCA3

ABCA17P RNA expression for individual tissues was determined by dot blot and quantitated using electronic autoradiography. The relative signal intensities were translated into a linear scale (0–4). -, not expressed.
