A differential diagnosis of GO with clinical phenotype overlap with other congenital disorder such as cutis laxa, Ehlers–Danlos' syndrome, Costello's syndrome, and the progeroid syndromes.14In conclusion, we report a GO patient with homozygous GORAB mutations with different clinical features that have not been reported before as tall stature and arachnodactyly and crowded teeth. This evidence concerns the gene GORAB and cutis laxa.
