A rare genetic overgrowth syndrome characterised by global developmental delay, macrosomia with subsequent somatic overgrowth, bilateral cystic lung lesions, congenital nephromegaly and bilateral Wilms tumour. Craniofacial dysmorphism includes macrocephaly, frontal bossing, large anterior fontanelle, mild hypertelorism, ear pit, flat nasal bridge, anteverted nares and mild micrognathia. Additional features may include brain and skeletal anomalies, enlarged protuberant abdomen, fat pads on dorsum of feet and toes, and rugated soles with skin folds, as well as umbilical/inguinal hernia and autistic behaviour. [from SNOMEDCT_US]

DICER1 tumor predisposition (DICER1) is characterized by an increased risk for pleuropulmonary blastoma (PPB), pulmonary cysts, thyroid gland neoplasia (multinodular goiter, adenomas, and/or thyroid cancer), ovarian tumors (Sertoli-Leydig cell tumor, gynandroblastoma, and sarcoma), and cystic nephroma. Less commonly observed tumors include ciliary body medulloepithelioma, nasal chondromesenchymal hamartoma, embryonal rhabdomyosarcoma, pituitary blastoma, pineoblastoma, central nervous system (CNS) sarcoma, other CNS tumors, and presacral malignant teratoid tumor. The majority of tumors occur in individuals younger than age 40 years. PPB typically presents in infants and children younger than age six years. Ovarian sex cord-stromal tumors are most often diagnosed before age 40 years. Cystic nephroma generally presents in young children but has also been reported in adolescents. Additional clinical features that may be seen include macrocephaly, ocular abnormalities, structural anomalies of the kidney and collecting system, and dental anomalies (bulbous crowns). [from GeneReviews]
