Evidence for haploinsufficiency phenotype
PubMed ID Description
24761742 This PMID corresponds to the GeneReviews for this condition, which provides a comprehensive overview of the variant spectrum.

Haploinsufficiency phenotype comments:

Heterozygosity for germline loss-of-function-type mutation (nonsense, frameshift, and exonic deletions) of DICER1 is associated with DICER1 syndrome, a familial tumor susceptibility syndrome characterized by increased susceptibility to develop several rare childhood tumors including pleuropulmonary blastoma; ovarian sex cord-stromal tumors (especially Sertoli-Leydig cell tumor); cystic nephroma; and thyroid gland neoplasias. Penetrance for these phenotypes is unknown, but appears to be reduced. As yet, whole gene deletion of DICER1 has not been reported.
