The effect on plasma fatty acid composition of 3-6 weeks feeding of standard diets supplemented with various omega 6 polyenoic fatty acids (18:2, 18:3, 20:3 or 20:4) was studied in two young brothers with multineuronal degeneration plus. These boys had mental retardation or maldevelopment, neurosensory hearing loss, retinitis pigmentosa, progressive muscular atrophy, hepatosplenomegaly and adrenal failure. The study objectives were to localize the site of metabolic block and to assess the safety and short-term clinical effect of dietary treatment. Our studies have shown that the low plasma levels of 20:4 omega 6 can be corrected by feeding ethyl arachidonate and that no adverse effects were experienced. A diet enriched in ethyl linoleate produced no obvious increases of 18:2 omega 6 metabolites, indicating that these patients do not have a linoleate deficiency in their omega 6 polyenoic fatty acid pathway. Lack of incorporation of 20:4 omega 6 and a retroconversion of 20:3 omega 6 to 18:2 omega 6 after a dihomo-gamma-linolenate-enriched diet suggest that a defect of delta 5 desaturase may be involved.

Thiamine-responsive megaloblastic anemia (TRMA) syndrome is an autosomal recessive disorder characterized by diabetes mellitus (DM), progressive sensorineural deafness, and thiamine-responsive anemia. Mutations in the SLC19A2 gene encoding a high-affinity thiamine transporter protein THTR-1 are responsible for the clinical features associated with TRMA syndrome. We report an African-American female with TRMA-syndrome associated with thyroid disease and retinitis pigmentosa caused by a novel mutation in the SLC19A2 gene. The patient presented at 12 months of age with paroxysmal atrial tachycardia and hepatosplenomegaly. One month later, she developed DM requiring intermittent insulin therapy. At 2-1/2 years of age, profound sensorineural hearing loss was discovered. By 4 years of age, daily insulin therapy (0.5 U/kg/day) was instituted and her insulin requirement gradually increased to 1.0 U/kg/day by 9 years of age. She developed optic atrophy, retinitis pigmentosa, and visual impairment by 12 years of age with severe restriction of peripheral vision by 16 years. At age 19, a thiamine-responsive normocytic anemia was discovered. She was diagnosed with autoimmune thyroiditis at 20 years and she experienced a psychotic episode associated with a mood disorder at age 21. With oral thiamine therapy, her insulin requirement decreased by 30% over a 20 month period. Molecular analysis revealed that the patient is homozygous for a missense mutation (C152T) in exon 1 of the SLC19A2 gene.

Congenital hepatic fibrosis is a rare cause of portal hypertension and esophageal varices in children. We report cases of siblings with biopsy proven congenital hepatic fibrosis and with atypical retinitis pigmentosa. They presented with repeated episodes of jaundice along with progressive decrease of vision in night. They had hepatosplenomegaly and portal hypertension with esophageal varices. One of the siblings had a large regenerating nodule replacing the entire right lobe of the liver and other one developed repeated hematemesis. This constellation of diagnosis belongs to the ciliopathy group of disorders. The spectrum of ciliopathy disorders has been evolving, and it varies from mild to severe manifestations.

SIFD describes a heritable, syndromic condition characterised principally by sideroblastic anaemia (SA) with immunodeficiency, fevers and developmental delay, arising in mutations within the TRNT1 gene. Other clinical manifestations of SIFD include cardiomyopathy, seizures, sensorineural hearing loss, renal dysfunction, metabolic abnormalities, hepatosplenomegaly and retinitis pigmentosa.Presentation of SIFD is variable but typically in early childhood with SA or with fever. In this report, we extend the described SIFD phenotype. We describe a kindred in which the index case presented with fetal hydrops, and early neonatal death, and the second child had severe anaemia at delivery. Both cases had prominent extramedullary erythropoiesis and numerous circulating nucleated red blood cells.
