orofaciodigital syndrome XI

An orofaciodigital syndrome that is characterized by blepharophimosis, bulbous nasal tip, broad nasal bridge, downslanting palpebral fissures, low set ears, skeletal malformations, intellectual deficits, deafness and congenital heart defects.

osteoglophonic dysplasia

An osteochondrodysplasia characterized by rhizomelic dwarfism, craniosynostosis, prominent supraorbital ridge, depressed nasal bridge, nonossifying bone lesions, and multiple unerupted teeth that has_material_basis_in heterozygous missense mutation in the FGFR1 gene on chromosome 8p11.23.

autosomal dominant Robinow syndrome 3

A Robinow syndrome characterized by autosomal dominant inheritance of mesomelia, genital hypoplasia, and distinctive facial features comprising frontal bossing, prominent eyes, and a depressed nasal bridge that has_material_basis_in heterozygous mutation in the DVL3 gene on chromosome 3q27.

syndromic X-linked intellectual disability 14

A syndromic X-linked intellectual disability characterized by mild to severe intellectual disability, autistic features, slender build, poor musculature, long, thin face, high-arched palate, high nasal bridge, and pectus deformities that has_material_basis_in mutation in the UPF3B gene on chromosome Xq24.

mucopolysaccharidosis I

A mucopolysaccharidosis characterized by a deficiency of the lysosomal enzyme alpha-L-iduronidase.

chromosome 15q26-qter deletion syndrome

A chromosomal deletion syndrome that is characterized by pre- and postnatal growth restriction, developmental delay, variable degrees of intellectual disability, brachy-clinodactyly, talipes equinovarus, nail hypoplasia, proximally placed digits and mild craniofacial dysmorphism including microcephaly, triangular face, broad nasal bridge and micrognathia.

chromosome 9p deletion syndrome

A chromosomal deletion syndrome characterized by trigonocephaly, flattened occiput midface hypoplasia, long philtrum, prominent forehead, broad flat nasal bridge, anteverted nares, malformed external ears, hypertelorism, hypertonia, delayed psychomotor development and that has_material_basis_in a contiguous gene deletion on the short arm of chromosome 9.

hyperphosphatasia with impaired intellectual development syndrome

An autosomal recessive intellectual developmental disorder characterized by hyperphosphatasia and intellectual disability. Distinctive facial features including hypertelorism, long palpebral fissures, a nose with a broad bridge and a rounded tip, downturned corners of the mouth, and a thin upper lip are also often observed.

PSPH deficiency

A serine deficiency that has_material_basis_in deficiency of phosphoserine phosphatase impeding the synthesis of L-serine.

rhizomelic chondrodysplasia punctata

A chondrodysplasia punctata that is characterized by disproportionately short stature primarily affecting the proximal parts of the extremities, a typical facial appearance including a broad nasal bridge, epicanthus, high-arched palate, dysplastic external ears, and micrognathia, congenital contractures, characteristic ocular involvement, dwarfism, and severe mental retardation with spasticity.
