[[http://www.uniprot.org/uniprot/XPA_HUMAN XPA_HUMAN]] Defects in XPA are a cause of xeroderma pigmentosum complementation group A (XP-A) [MIM:[http://omim.org/entry/278700 278700]]; also known as xeroderma pigmentosum type 1 (XP1). XP-A is a rare human autosomal recessive disease characterized by solar sensitivity, high predisposition for developing cancers on areas exposed to sunlight and, in some cases, neurological abnormalities. Group A patients show the most severe skin symptoms and progressive neurological disorders.<ref>PMID:1339397</ref> <ref>PMID:1372103</ref> <ref>PMID:9671271</ref>

[[http://www.uniprot.org/uniprot/XPA_HUMAN XPA_HUMAN]] Involved in DNA excision repair. Initiates repair by binding to damaged sites with various affinities, depending on the photoproduct and the transcriptional state of the region. Required for UV-induced CHEK1 phosphorylation and the recruitment of CEP164 to cyclobutane pyrimidine dimmers (CPD), sites of DNA damage after UV irradiation.<ref>PMID:19197159</ref>
