Targeted sequencing of known cardiomyopathy genes in the index patient identified a second mutation, a 1.7 Mp deletion that spans the <i>MYBPC3</i> gene.<b>Conclusions</b>: We report a pedigree with aniridia and other systemic abnormalities that were initially suspicious for a contiguous-gene syndrome like WAGR.
Our previous study of congenital aniridia patients revealed a noticeable number of aniridia patients with WAGR-region deletions but without Wilms' tumor in their medical history.
The patient is examined in light of other reported patients with deletions and/or translocations involving the regions between 11p12 --> 11p14 including patients with WAGR + obesity (WAGRO) as well as with other reported patients with aniridia and congenital ptosis.
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).
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).
