| Identified Mutation |
5BP DEL; Satokata et al. [Mutat. Res. 273: 193-202, (1992)] found a 5-bp deletion (C349-T353) in exon 5 which causes a frameshift that results in the replacement of the sequence leu-met-asn (amino acids 117-119) by glu-pro-leu, followed by translation termination. |

278700.0002; XERODERMA PIGMENTOSUM, TYPE A |
| Identified Mutation |
CYS108PHE; In the patient represented by the cell line GM02009, Satokata et al. [Mutat. Res. 273: 193-202, (1992)] found compound heterozygosity for 2 mutations: a 5-bp deletion C349-T353) in exon 5 causing a frameshift that resulted in the replacement of the sequence leu-met-asn (amino acids 117-119) by glu-pro-leu, followed by translation termination; and a G-to-T transversion at nucleotide 323 altering the cys-108 codon (TGT) to a phe codon (TTT) that resulted in disruption of a putative zinc finger domain of the XPA protein. |
| Remarks |
XP1PD; mental and growth retardation; photosensitivity; similarly affected sib; the donor subject is a compound heterozygote for two mutations in the XPA gene: one allele carries a 5 bp deletion (CTTAT) at nucleotides 349-353 of exon 3 which causes a frameshift that results in the replacement of the sequence leu-met-asn (amino acids 117-119) by glu-pro-leu, followed by translation termination; the second allele carries a G-to-T transversion at nucleotide 323 of exon 3 altering the Cys-108 codon (TGT) to a phe codon (TTT) that results in disruption of a putative zinc finger domain of the XPA protein [Cys108Phe (C108F)]. |
