Xeroderma pigmentosum (XP) is a rare autosomal recessive disorder characterized by defective nucleotide excision repair (NER), leading to extreme sensitivity to sunlight-induced skin pigmentation changes and increased skin cancer risk. XP patients present with varying severity, often influenced by specific variants in NER-associated genes. Here, we describe two unrelated Cypriot XP-A patients with a mild phenotype linked to a homozygous missense variant (c.389G>A, p.R130K). The older patient, aged 69, developed progressive neurological degeneration in his 40s, while the younger patient, aged 32, has no neurological abnormalities to date. Molecular analysis revealed a severe transcription-coupled NER (TC-NER) defect and reduced global genome repair (GG-NER) in patient fibroblasts, consistent with the XP-A diagnosis. Surprisingly, very low XPA protein levels were detected, despite the conservative amino acid substitution. Further experiments demonstrated that while the XPA

A splicing variant in XPA results in delayed onset of clinical features of xeroderma pigmentosum.
