Frontal bossing, and Prominent forehead

Acromesomelic dysplasia, Maroteaux type is an autosomal recessively inherited form of acromesomelic dysplasia (see this term) characterized by severe dwarfism (adult height >120 cm), both axial and appendicular involvement (shortening of the middle and distal segments of limbs and vertebral shortening), and with normal facial appearance and intelligence. It is a less severe form than acromesomelic dysplasia, Grebe type and acromesomelic dysplasia, Hunter-Thomson type (see these terms).

Although the phenotypic spectrum and severity of FG syndrome is wide, the cardinal features include congenital hypotonia, delayed speech development, relative macrocephaly, dysmorphic facies, and anal anomalies or severe constipation (Unger et al., 2007).For a general phenotypic description and a discussion of genetic heterogeneity of FG syndrome, see FGS1 (OMIM ).

Macrocephaly-developmental delay syndrome is a rare, intellectual disability syndrome characterized by macrocephaly, mild dysmorphic features (frontal bossing, long face, hooded eye lids with small, downslanting palpebral fissures, broad nasal bridge, and prominent chin), global neurodevelopmental delay, behavioral abnormalities (e.g. anxiety, stereotyped movements) and absence or generalized tonic-clonic seizures. Additional features reported in some patients include craniosynostosis, fifth finger clinodactyly, recurrent pneumonia, and hepatosplenomegaly.

The Maroteaux type of mesomelic sysplasia is an autosomal recessive disorder characterized by severe dwarfism (height below 120 cm) with shortening of the middle and distal segments of the limbs. This condition is usually diagnosed at birth and becomes more obvious in the first 2 years of life. X-rays show short broad fingers, square flat feet, and shortening of the long bones (particularly the forearms). The radius is bowed; the ulna is shorter than the radius, and its distal end is occasionally hypoplastic. The skull is dolichocephalic and a shortness of the trunk, with decreased vertebral height and narrowing of the lumbar interpedicular distances, is consistently observed. Facial appearance and intelligence are normal (summary by Faivre et al., 2000).
