Orphanet: ORPHA388

Targets

ETB receptor
Comments:  Hirschsprung disease is characterized by an absence of enteric ganglia in the distal colon and a failure of innervation in the gastrointestinal tract

Mutations in the receptor gene: a transversion, C to A, at nucleotide 1170 (S390R) results in impairment of cell signalling when expressed in CHO cells, and a transition, T to C, at nucleotide 325 (C109R), results in the receptor not translocating to the plasma membrane. Both may contribute to the disease.

Mutant (W276C) receptor exhibited partial impairment of function.
