Skin and ocular symptoms are confined to sun exposed areas of the body. Patients have markedly increased risk for UV-induced skin, ocular, and oral cancers. Some patients develop neurodegenerative symptoms, including diminished tendon reflexes and microcephaly. In this study, we describe clinical and genetic findings of 36 XP patients from Egypt, a highly consanguineous population from North Africa. Thorough clinical evaluation followed by Sanger sequencing of XPA and XPC genes were done. Six novel and seven previously reported mutations were identified. Phenotype-genotype correlation was investigated. We report clinical and molecular findings consistent with previous reports of countries sharing common population structure, and geographical and historical backgrounds with implications on common ancestral origins and historical migration flows. Clinical and genetic profiling improves diagnosis, management, counselling, and implementation of future targeted therapies.<\/jats:p>","DOI":"10.3390\/genes12020295","type":"journal-article","created":{"date-parts":[[2021,2,21]],"date-time":"2021-02-21T21:15:01Z","timestamp":1613942101000},"page":"295","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Clinical and Mutational Spectrum of Xeroderma Pigmentosum in Egypt: Identification of Six Novel Mutations and Implications for Ancestral Origins"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1913-4650","authenticated-orcid":false,"given":"Eman","family":"Rabie","sequence":"first","affiliation":[{"name":"Medical Molecular Genetics Department, Human Genetics &amp; Genome Research Division (HGGR), National Research Centre (NRC), Cairo 12622, Egypt"},{"name":"Biology Department, School of Sciences and Engineering, The American University in Cairo (AUC), Cairo 11835, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Khalda","family":"Amr","sequence":"additional","affiliation":[{"name":"Medical Molecular Genetics Department, Human Genetics &amp; Genome Research Division (HGGR), National Research Centre (NRC), Cairo 12622, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suher","family":"Zada","sequence":"additional","affiliation":[{"name":"Biology Department, School of Sciences and Engineering, The American University in Cairo (AUC), Cairo 11835, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heba","family":"El-Sayed","sequence":"additional","affiliation":[{"name":"Clinical Genetics Department, HGGR, NRC, Cairo 12622, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamad","family":"El Darouti","sequence":"additional","affiliation":[{"name":"Dermatology Department, Faculty of Medicine, Cairo University, Cairo 12613, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ghada","family":"El-Kamah","sequence":"additional","affiliation":[{"name":"Clinical Genetics Department, HGGR, NRC, Cairo 12622, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"168","DOI":"10.1136\/jmg.2010.083022","article-title":"Cancer and neurologic degeneration in xeroderma pigmentosum: Long term follow-up characterises the role of DNA repair","volume":"48","author":"Bradford","year":"2010","journal-title":"J.
