The other trinucleotide repeat: polyalanine expansion disorders.

Abstract excerpt

Expansions of trinucleotide repeats encoding polyalanine tracts have been recognized as the cause of several diseases, predominantly congenital malformation syndromes. To date, nine genes with alanine tract expansions have been described. With the exception of PABPN1, which codes for a poly(A)-binding protein, all these genes encode transcription factors that play important roles during development. Recent in...
