Asymptomatic
HCP was first described by Berger and Goldberg in 1955 and was considered an asymptomatic biochemical abnormality. [ncbi.nlm.nih.gov]
The condition is usually asymptomatic, but acute attacks resembling those of acute intermittent porphyria can occur. cop·ro·por·phyr·i·a ( kop'rō-pōr-fir'ē-ă ), [MIM*121300] Presence of coproporphyrins in the urine, as in variegate porphyria. coproporphyria [medical-dictionary.thefreedictionary.com]
Identification of asymptomatic patients allows them to adjust their lifestyle to avoid common triggering factors. [2] [7] References [ edit ] a b c d e f "#121300 COPROPORPHYRIA, HEREDITARY; HCP". Johns Hopkins University. [en.wikipedia.org]
For asymptomatic individuals, the urine studies may be normal, but a fecal porphyrin analysis will show elevation of coproporphyrin III. Screening tests of this kind should be confirmed by DNA analysis to confirm a CPOX mutation. [porphyriafoundation.blogspot.com]
