MLGA: a cost-effective approach to the diagnosis of gene deletions in eye development anomalies.

Whole gene deletions or duplications are an important cause of genetic disease and phenotypic variation. Targeted techniques for the routine testing of gross rearrangements have become essential tools for diagnostic researchers with the search for the most cost-effective and efficient tool assuming high priority. We used the new selector technique, MLGA (multiplex ligation-dependent genome amplification), to confirm deletions in two genes, SOX2 (SRY [sex determining region Y]) box 2) and OTX2 (orthodenticle homeobox 2), in individuals with developmental eye disease. We conclude that MLGA has the potential to be a useful technique in diagnostic research for the identification of deletions or duplications of known genes due to its speed and relatively low cost.
