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. WD repeat domain 11 (WDR11), located at 10q25–26, was recently identified as a causative gene in hypogonadotropic hypogonadism, but other clinical phenotypes caused by WDR11 variants have not been identified. In this study, we have identified a WDR11 missense mutation, NM_018117.11: c.2108G > A; p.(Arg703Gln); ClinVar accession SCV000852064, in a two-year-old boy with severe growth retardation, ventricular septal defect, and coloboma symptoms. The case suggests that WDR11 is partially responsible for the clinical features of 10q26 deletion syndrome and provides novel insights into the pathophysiology of this syndrome.
