Objective

To investigate the wide variability of ocular manifestations associated with mutations in the COL4A1 gene that encodes collagen IValpha1.

Methods

We clinically evaluated 7 patients from 2 unrelated families in whom ocular features segregated with COL4A1 mutations that were identified by direct sequencing.

Results

The G2159A transition (c.2159G>A) that leads to the missense mutation p.Gly720Asp was identified in family A. An ocular phenotype of variable severity was observed in all affected relatives. The missense mutation c.2263G>A, p.Gly755Arg was identified in family B. One patient from family B also displayed notable ocular features.

Conclusions

The COL4A1 mutations may be associated with various ophthalmologic developmental anomalies of anterior segment dysgenesis type, which are reminiscent of Axenfeld-Rieger anomalies (ARA). Cerebrovascular disorders should be added to the list of signs potentially associated with ARA.

Clinical relevance

These data suggest that cerebral magnetic resonance imaging may be recommended in the clinical treatment of patients with apparently isolated ARA, even when neurological symptoms or signs are lacking."xsd:string
