Abstract/OtherAbstract:
We report a child presenting with Alagille and Wolff-Parkinson-White (WPW) syndromes. Standard karyotyping showed a de novo 46,XY,t(1;6)(p31;q16) translocation. Fluorescent in situ hybridization analysis identified a de novo deletion in the 20p12 chromosomal region encompassing JAG1, the major gene responsible for Alagille syndrome. The aberration was further characterized using an Agilent 44K oligonucleotide array, which confirmed the 4.95Mb 20p12 deletion. An additional 8.26Mb deletion was identified at the 6q16 translocation breakpoint. To our knowledge, WPW has never been associated with Alagille syndrome. The patient we describe presented with a 6q16 deletion containing 21 genes but no good candidate genes for WPW. The 20p12 deletion included 19 genes among them JAG1 and BMP2. Recently, two unrelated patients with WPW and BMP2 deletions have been reported. Despite a relationship between WPW and JAG1 deletion cannot be excluded, the JAG1 deletion is unlikely responsible for the ventricular preexcitation since WPW has never been associated with Alagille syndrome. Among the other deleted genes in 20p12, BMP2 appears to be a good candidate responsible for the WPW.
