Hemochromatosis gene sequence deviations in German patients with porphyria cutanea tarda.

Precipitating factors of porphyria cutanea tarda in Brazil with emphasis on hemochromatosis gene (HFE) mutations. Study of 60 patients*

BACKGROUND Porphyria cutanea tarda is the most common form of porphyria, characterized by the decreased activity of the uroporphyrinogen decarboxylase enzyme. Several reports associated HFE gene mutations of hereditary hemochromatosis with porphyria cutanea tarda worldwide, although up to date only one study has been conducted in Brazil. OBJECTIVES Investigation of porphyria cutanea tarda ass...

Primary hemochromatosis presented by porphyria cutanea tarda: a case report

We present a 27-year-old female Caucasian patient, who initially presented with extensive fragility and blistering of mainly the dorsal side of both hands. Histology and urine porphyrin analysis confirmed the diagnosis of porphyria cutanea tarda. Internal screening for underlying disease revealed C282Y mutation-associated primary hemochromatosis, a hereditary iron-overload syndrome that may cau...

Familial and sporadic porphyria cutanea tarda: clinical, biochemical and genetic features with emphasis on iron status.

The manifestation of porphyria cutanea tarda reflects genetic and environmental factors. Mutations in the uroporphyrinogen decarboxylase gene, located at chromosome 1p34, discriminate familial porphyria cutanea tarda from sporadic cases. Furthermore, mutations in the haemochromatosis gene may be involved in the aetiology. In this study 53 unrelated Danish patients with porphyria cutanea tarda w...

Complex pattern of alternative splicing in the normal uroporphyrinogen decarboxylase gene: implications for diagnosis of familial porphyria cutanea tarda.

We describe multiple alternative transcripts of uroporphyrinogen decarboxylase mRNA in normal individuals and patients with familial porphyria cutanea tarda. mRNA was reverse-transcribed, subjected to the polymerase chain reaction, and analyzed for nucleotide sequence. Seven different transcripts were characterized, and a cryptic splice acceptor site was identified in intron 1. In all mRNAs the...
