A balanced translocation t(6;14)(q25.3;q13.2) leading to reciprocal fusion transcripts in a patient with intellectual disability and agenesis of corpus callosum.

Abstract

We identified a male patient presenting with intellectual disability and agenesis of the corpus callosum, carrying an apparently balanced, reciprocal, de novo translocation t(6;14)(q25.3;q13.2). Breakpoint mapping, using array painting, identified 2 interesting candidate genes, ARID1B and MRPP3, disrupted in the patient. Unexpectedly, the rearrangement produced 3 in-frame reciprocal fusion transcripts that were further characterized. Formation of fusion transcripts is mainly reported in acquired malignancies and is very rarely observed in patients with intellectual disability (ID) and/or multiple congenital malformations (MCA). Additional experimental results suggest that ARID1B, a gene involved in chromatin remodeling, constitutes a good candidate for the central nervous system phenotype present in the patient.
