Hartnup disease is a rare metabolic disorder belonging to the neutral aminoacidurias and characterized by abnormal renal and gastrointestinal transport of neutral amino acids (tryptophan, alanine, asparagine, glutamine, histidine, isoleucine, leucine, phenylalanine, serine, threonine, tyrosine and valine).

Low match PROTOPORPHYRIA, ERYTHROPOIETIC, 1; EPP1

Erythropoietic protoporphyria-1 is an inborn error of porphyrin metabolism caused by decreased activity of the enzyme ferrochelatase, the terminal enzyme of the heme biosynthetic pathway, which catalyzes the insertion of iron into protoporphyrin to form heme. EPP is characterized clinically by photosensitivity to visible light commencing in childhood, and biochemically by elevated red cell protoporphyrin levels (Todd, 1994). Genetic Heterogeneity of Erythropoietic ProtoporphyriaAlso see X-linked erythropoietic protoporphyria (XLEPP ), caused by mutation in the ALAS2 gene (OMIM ) on chromosome Xp11, and EPP2 (OMIM ), caused by mutation in the CLPX gene (OMIM ) on chromosome 15q22.

Low match PORPHYRIA CUTANEA TARDA

Porphyria cutanea tarda (PCT) is characterized by light-sensitive dermatitis and the excretion of large amounts of uroporphyrin in urine (Elder et al., 1980).De Verneuil et al. (1978) and others classified porphyria cutanea tarda, the most common type of porphyria, into 2 types: type I (OMIM ), or 'sporadic' type, associated with approximately 50% level of uroporphyrinogen decarboxylase (UROD) in liver (Elder et al., 1978; Felsher et al., 1982), and type II, or 'familial' type, characterized by 50% deficient activity of the same enzyme in many tissues (Kushner et al., 1976; Elder et al., 1980).PCT type II is an autosomal dominant disorder with low penetrance and constitutes about 20% of cases of PCT. Recognized exacerbating factors of PCT include iron overload, excessive use of alcohol, exposure to polyhalogenated aromatic chemicals, exposure to estrogens, chronic viral hepatitis C, HIV infections, and mutation in the HFE gene (OMIM ) that are responsible for hereditary hemochromatosis (OMIM ) (review by Lambrecht et al., 2007).

Low match PEELING SKIN SYNDROME 2; PSS2

Peeling skin syndrome (PSS) is an autosomal recessive genodermatosis characterized by the shedding of the outer epidermis. In an acral form of the disorder (PSS2), the dorsa of the hands and feet are predominantly affected, and ultrastructural analysis shows separation at the junction between the granular cells and the stratum corneum in the outer epidermis (summary by Cassidy et al., 2005).For a discussion of genetic heterogeneity of peeling skin syndrome, see PSS1 (OMIM ).
