Genetic Basis <strong>of</strong> Thoracic <strong>Aortic</strong> Aneurysms 105<br />

Figure 2 (See color insert) Variable clinical presentation <strong>of</strong> individuals with transforming<br />

growth factor β receptor (TGFBR1 or TGFBR2) mutations. Individuals may present with hypertelorism<br />

and malar flattening (A); bifid uvula (B); marked hypertelorism with exotropia (C);<br />

premature fusion <strong>of</strong> the coronal suture <strong>of</strong> the skull (arrow, D); marked tortuosity <strong>of</strong> the aorta<br />

(arrow head ), aortic root and subclavian artery aneurysms (arrows) or tortuous abdominal aorta<br />

(arrow) (E,F,H); micrognathia, retrognathia, downslanting palpebral fissures, and skeletal<br />

features including pectus excavatum, scoliosis, and pes planus (G,I,J). Source: From Refs. 21, 51.<br />

Figure 3 Heterozygous germline transforming growth factor β receptor TGFBR1 and<br />

TGFBR2 mutations in syndromic and nonsyndromic aortic disease. Genomic and protein<br />

structure <strong>of</strong> the TGFBR1 and TGFBR2 genes showing known mutations previously identified<br />

in MFS, LDS, Furlong syndrome, and TAAD. Source: From Ref. 58.
