" /> Perlman syndrome - CISMeF





Preferred Label : Perlman syndrome;

Symbol : PRLMNS;

CISMeF acronym : PRLMNS;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : Nephroblastomatosis, fetal ascites, macrosomia, and wilms tumor; Renal hamartomas, nephroblastomatosis, and fetal gigantism;

Description : Perlman syndrome is an autosomal recessive congenital overgrowth syndrome with similarities to Beckwith-Wiedemann syndrome (BWS; 130650). Affected children are large at birth, are hypotonic, and show organomegaly, characteristic facial dysmorphisms (inverted V-shaped upper lip, prominent forehead, deep-set eyes, broad and flat nasal bridge, and low-set ears), renal anomalies (nephromegaly and hydronephrosis), frequent neurodevelopmental delay, and high neonatal mortality. Perlman syndrome is associated with a high risk of Wilms tumor, with a 64% incidence in infants surviving beyond the neonatal period. The tumor is diagnosed at an earlier age in these individuals compared with sporadic cases (less than 2 years and 3-4 years of age, respectively), and there is a high frequency of bilateral tumors (55%). Histologic examination of the kidneys in children with Perlman syndrome shows frequent nephroblastomatosis, which is a precursor lesion for Wilms tumor (summary by Astuti et al., 2012).;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the DIS3 like 3'-5' exoribonuclease 2 gene (DIS3L2, 614184.0001);

Prefixed ID : #267000;
