| A rare neurodegenerative disorder belonging to the group of infantile progressive encephalopathies. Onset occurs during the first few weeks or months of life with hypotonia, poor feeding, drowsiness and abnormal movements. Infantile spasms, hypsarrhythmia and seizures appear during the first year of life. Visual loss, abnormal eye movements and optic atrophy also occur during infancy. Transmission appears to be autosomal recessive. A significant number of patients have been described who displayed most of the diagnostic criteria and features of PEHO syndrome, but did not appear to have cerebral atrophy on MRI, lacked the ophthalmologic signs and showed no reduction in CSF IGF-1 levels. This group of patients was diagnosed with PEHO-like syndrome. The prognosis is poor and most patients die before 15 years of age, mainly as a result of pneumonia or aspiration. |

| A form of genetic LCAT (lecithin-cholesterol acyltransferase) deficiency characterised clinically by corneal opacifications, and biochemically by significantly reduced HDL cholesterol and partial LCAT enzyme deficiency. The disease is very rare. Corneal opacities are progressive and are observed from an early age (adolescence or young adulthood) and sometimes result in visual impairment. These lesions are generally more severe than in complete LCAT deficiency and form a mosaic pattern of small dot-like grey-white opacities. Signs of atherosclerosis have only been reported in rare cases although patients have low HDL cholesterol levels. In patients with this disorder, alpha-LCAT activity is abolished, but beta-LCAT activity is preserved. Impaired enzyme function is thought to result in deposition of lipids in the cornea. The disease follows an autosomal recessive pattern of inheritance. |
