congenital aniridia
Postnatal manipulation of Pax6 dosage
reverses congenital tissue malformation defects
Differential Diagnoses
Gillespie syndrome
Congenital nystagmus
Juvenile gluacoma
Congenital cataracts
Renal ultrasounds to detect tumors and anomalies of the kidneys indicative of WAGR syndrome
Fluorescent in situ hybridization (FISH) used to detect deletions in Wilm tumor genes
Genetic testing for deletions/mutations in chromosomes and genes specific to the condition
Causes
