Figure 2. Two subgroups of MBS. Clinical features of MBS cluster to form two subgroups of MBS. Type 1 MBS tends to exhibit limb abnormalities, micrognathia, and swallowing difficulties. Nearly two-thirds of patients exhibiting any one of the marked features (*) had all three of those features. Type 2 MBS is more likely to include developmental delay, additional cranial nerve palsies, and palatal and brain imaging abnormalities, but the clustering is weaker.
