The scapula and the clavicle, the bones that form the shoulder girdle, were also significantly affected: the scapula was longer, the clavicle was shorter and both bones showed increased bone volumes in Fgfr2+/P253R Apert syndrome mice (Table 1 and Figure 1G) compared to unaffected littermates. The gene discussed is FGFR2; the disease is Apert syndrome.
