Summary

Excerpted from the GeneReview: Serine Deficiency Disorders
Serine deficiency disorders include a spectrum of disease ranging from lethal prenatal-onset Neu-Laxova syndrome to serine deficiency with infantile, juvenile, or adult onset. Neu-Laxova syndrome is characterized by severe intrauterine growth deficiency, microcephaly, congenital bilateral cataracts, characteristic dysmorphic features, limb anomalies, and collodion-like ichthyosis. Infants are typically stillborn or die in early infancy. Infantile-onset serine deficiency is characterized by seizures, microcephaly, developmental delay, intellectual disability, and spastic quadriplegia. Individuals that present with juvenile-onset serine deficiency have seizures and many develop spastic quadriplegia. Adult-onset serine deficiency is characterized by progressive axonal polyneuropathy with ataxia and possible cognitive impairment.
