| Chromosomal Location |
13q33 |
| Allelic Variant 1 |
133530.0004; XERODERMA PIGMENTOSUM, GROUP G COMBINED WITH COCKAYNE SYNDROME |
| Identified Mutation |
1-BP DEL, FS660TER; Nouspikel et al. (1997) studied a girl with psychomotor retardation and microcephaly who died at 6.5 years of age. She was severely sunlight-sensitive with several pigmented cutaneous spots (Jaeken et al., 1989; Vermeulen et al., 1993). She was lacking a single nucleotide within an AAA triplet at nucleotides 2170-2172, which resulted in a TGA stop codon after amino acid 659. Such a deletion was considered characteristic of a slippage error during DNA replication. The patient appeared to be homozygous for this truncation mutation.

| Remarks |
XPCS1LV; clinical characteristics of Cockayne syndrome with biochemical defect typical of XP; severe psychomotor retardation; microcephaly; skin very sensitive to sunlight; salt-and-pepper retinal pigmentation; retinal artery narrowing; donor subject is homozygous for a 1 bp deletion in an AAA triplet at nucleotides 2170_2172 of the ERCC5 gene resulting in a TGA stop codon after amino acid 659 (fs660Ter) |
