Q.2 What is accumulated ?
• Patients with disease are unable to degrade phytanic acid because of a deficient activity of phytanoyl-CoA hydroxylase
(PhyH), a peroxisomal enzyme catalyzing the first step of phytanic acid alpha-oxidation.
• It is an autosomal recessive trait
• There is complex developmental sequelae, and progressive disabilities.
• Peripheral polyneuropathy, cerebellar ataxia, , retinits pigmentosa and ichthyosis are the major clinical components. The
symptoms evolve slowly and insidiously from childhood through adolescence and early adulthood.
• Symptoms begin by late childhood or adolescence, although there are reports of presentation as late as 50 years of age.
• Disease presents with anosmia and early-onset retinitis pigmentosa, with variable neuropathy, deafness, ataxia and
ichthyosis.
• Treatment
• Phytanic acid is obtained from the diet, particularly from meat and dairy products. Dietary restriction helps to control
sensory neuropathy, myopathy, ataxia and ichthyosis. In acute presentation
