Imprinting syndrome
Witryna1 wrz 2006 · In the case of Von Hippel–Lindau syndrome, hypomelanosis of Ito and dermatopathia pigmentosa reticularis, imprinting may play a part in the inheritance. With neurofibromatosis type 1, a nonimprinted condition, the expression of the phenotype could be affected by interaction with imprinted gene loci.
