278700.0003; XERODERMA PIGMENTOSUM, TYPE A |
| 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. |

| Allelic Variant 2 |
new splice site; XERODERMA PIGMENTOSUM, COMPLEMENTATION GROUP A |
| Identified Mutation |
A>G change in intron 3 |
| Remarks |
The donor shows mild skin features of XP and definite neurological developmental delay. Family history is negative. The biopsy was taken antemortem on 4/26/83 from skin of the forearm. The culture was initiated using explants of minced skin tissue. The cell morphology is fibroblastlike. The donor subject carries two mutations in the XPA gene: a 5 bp deletion (349del5) in exon 3 which causes a frameshift and an A-to-G change in intron 3 which results in a new splice site. |
