Rare De Novo Missense Variants in RNA Helicase DDX6 Cause Intellectual Disability and Dysmorphic Features and Lead to P-Body Defects and RNA Dysregulation.
De Novo Variants in WDR37 Are Associated with Epilepsy, Colobomas, Dysmorphism, Developmental Delay, Intellectual Disability, and Cerebellar Hypoplasia.
The Wilms tumour (WT1) gene was first localized through its deletion in individuals with the WAGR syndrome (Wilms tumour, aniridia, genitourinary abnormalities and mental retardation).
A point mutation found in the WT1 gene in a sporadic Wilms' tumor without genitourinary abnormalities is identical with the most frequent point mutation in Denys-Drash syndrome.
All four del(11)(p13) cases presented with WAGR, a complex syndrome associated with a predisposition to Wilms' tumor (WT), aniridia (A), genitourinary abnormalities (G), and mental retardation (R).
All patients had failure to thrive and some of the classic syndromic features of G6PC3 deficiency, including cardiac abnormalities and visibility of superficial veins in all, endocrinologic problems in PI and PIII, and urogenital abnormalities in PII.
Glucose-6-phosphatase catalytic subunit 3 (G6PC3) deficiency is a newly described syndromic type of severe congenital neutropenia, associated with multiple organ abnormalities including facial, cardiac, and urogenital abnormalities, and increased visibility of superficial veins.
