The contiguousABCD1/DXS1375E (BCAP31) deletion syndrome (CADDS) is a rare X-linked contiguous gene deletion syndrome with a severe clinical phenotype that includes marked delays, significant growth failure, liver dysfunction, and early death. The X-linked creatine transporter deficiency is a considerably more common and a cause of X-linked intellectual disability; however, multi-exon deletions of the creatine transporter are rare. We report the fifth case of CADDS, who also has a deletion of the Xlinked creatine transporter. We also review reported cases of deletions in this region in order to clarify the clinical spectrum of contiguous microdeletions in this region.
