Fig. 4From: FGFR3 gene mutation plus GRB10 gene duplication in a patient with achondroplasia plus growth delay with prenatal onsetOverview of previously described cases shown to have genomic imbalances at 7p12.1 that involved GRB10. (Blue: duplications). Red vertical lines demarcate the genomic interval of the GRB10 gene (a). Scatter plot of a Cytoscan HD array at 7p12.1 showing a duplication interval involving the whole GRB10 gene and part of the COBL gene (b)Back to article page
