MRN: 91036918

6 y.o. black female

Research

Recurrent progressive anterior segment fibrosis syndrome following a descemet‑stripping endothelial keratoplasty in an infant with 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

Mutations of AN1 and AN2 genes

Chromosomal deletion of p13 on chromosome 11

Mutation in PAX6 gene
