# Case report: Xeroderma pigmentosum Group A with erythropoietic protoporphyria in a young Chinese patient

## TL;DR

A young Chinese patient has both xeroderma pigmentosum Group A and erythropoietic protoporphyria, a rare combination of genetic skin disorders.

## Contribution

First reported case of xeroderma pigmentosum Group A with erythropoietic protoporphyria in a Chinese patient.

## Key findings

- Patient had XPA Met214AsnfsTer7 frameshift mutation.
- Patient carried a homozygous splicing mutation c.315–48T>C in FECH intron3.

## Abstract

Xeroderma pigmentosum is a rare autosomal recessive genodermatoses characterized by a deficiency in nucleotide excision repair. Erythropoietic protoporphyria is a rare inherited metabolic disease caused by the perturbation of heme. Xeroderma pigmentosum-erythropoietic protoporphyria is exceedingly rare. Hereby, we firstly report a young Chinese patient of xeroderma pigmentosum Group A with erythropoietic protoporphyria carrying an XPA Met214AsnfsTer7 frameshift mutation and a homozygous splicing mutation, c.315–48T>C, in the proband’s intron3 of FECH.
