WDR11 is another causative gene for coloboma, cardiac anomaly and growth retardation in 10q26 deletion syndrome.

10q26 deletion syndrome is caused by a rare chromosomal abnormality, and patients with this syndrome present with an extensive and heterogeneous phenotypic spectrum. Several genes, such as EMX2 and FGFR2, were identified as the cause genital anomalies and facial dysmorphism in 10q26 deletion syndrome. However, the critical region for 10q26 deletion syndrome is not determined and the precise relationships between the causative genes and the phenotypes are still controversial.
