| Microcephalic primordial dwarfism due to ZNF335 deficiency is characterized by severe antenatal microencephaly, simplified gyration, agenesis of the corpus callosum, absence of basal ganglia (very rare), pontocerebellar atrophy and involvement of the white matter with secondary cerebral atrophy. Congenital cataract, choanal atresia, multiple arthrogryposis and spastic tetraparesis can occur. |

| Metaphyseal dysplasia-maxillary hypoplasia-brachydactyly syndrome is characterized by metaphyseal dysplasia associated with short stature and facial dysmorphism (a beaked nose, short philtrum, thin lips, maxillary hypoplasia, dystrophic yellowish teeth) and acral anomalies (short fifth metacarpals and/or short middle phalanges of fingers two and five). It has been described in several members spanning four generations of a French-Canadian family. The syndrome is likely to be transmitted as an autosomal dominant trait. |

| Metaphyseal chondromatosis with D-2-hydroxyglutaric aciduria is an extremely rare genetic disorder characterized by the unique association of enchondromatosis with D-2 hydroxyglutaric aciduria. Clinical features include enchondromatosis (with short stature, severe metaphyseal dysplasia and mild vertebral involvement), elevated levels of urinary 2-hydroxyglutaric acid and mild developmental delay. |

| A rare non-syndromic syndactyly characterized by mesoaxial reduction of fingers, complete syndactyly of the 3rd and 4th fingers with synostoses of the corresponding metacarpals and associated single phalanges, malformed thumbs, and hypoplasia and clinodactyly of the 5th finger. Preaxial webbing of toes with terminal phalangeal hypoplasia of all toes has been reported in association. |
