Spectrum of mutations and genotype-phenotype analysis in Currarino syndrome.

Abstract excerpt

The triad of a presacral tumour, sacral agenesis and anorectal malformation constitutes the Currarino syndrome which is caused by dorsal-ventral patterning defects during embryonic development. The syndrome occurs in the majority of patients as an autosomal dominant trait associated with mutations in the homeobox gene HLXB9 which encodes the nuclear protein HB9. However, genotype-phenotype analyses have been...
