Among the various sequence repeats that shape the human genome, trinucleotide repeats have attracted special interest as a result of their involvement in a class of human genetic disorders known as triplet repeat expansion diseases. Recently, long TGG repeat tracts were shown to be implicated in a genomic disorder resulting from chromosome 14q32.2 deletion. Various different mechanisms might trigger this deletion, and looking at the problem from a structural biology perspective may help. Deeper insight into repeated sequences and their features may shed light on the mechanisms involved in this microdeletion and similar genomic rearrangements.
