Dihydropteridine reductase (DHPR) deficiency is a severe form of hyperphenylalaninemia (HPA) due to impaired regeneration of tetrahydrobiopterin (BH4) (see this term), leading to decreased levels of neurotransmitters (dopamine, serotonin) and folate in cerebrospinal fluid, and causing neurological symptoms such as psychomotor delay, hypotonia, seizures, abnormal movements, hypersalivation, and swallowing difficulties.

Immunodeficiency-centromeric instability-facial anomalies syndrome-4 is an autosomal recessive disorder characterized by recurrent infections in childhood and variable dysmorphic facial features. Laboratory studies show hypomethylation of certain chromosomal regions. Additional features, including delayed development, are variable (summary by Thijssen et al., 2015).For a discussion of genetic heterogeneity of immunodeficiency-centromeric instability-facial anomalies syndrome, see ICF1 (OMIM ).

Autosomal recessive spastic paraplegia type 70 is a very rare, complex subtype of hereditary spastic paraplegia that presents in infancy with delayed motor development (i.e. crawling, walking) and is characterized by lower limb spasticity, increased deep tendon reflexes, extensor plantar responses, impaired vibratory sensation at ankles, amyotrophy and borderline intellectual disability. Additional signs may include gait disturbances, Achilles tendon contractures, scoliosis and cerebellar abnormalities.

EIEE52 is an autosomal recessive seizure disorder characterized by infantile onset of refractory seizures with resultant delayed global neurologic development that causes intellectual disability and other persistent neurologic abnormalities (summary by Patino et al., 2009).For a general phenotypic description and a discussion of genetic heterogeneity of EIEE, see EIEE1 (OMIM ).
